Adding Sport Mode to a 987.2 Base

Heh: most people who haven't tried one say exactly that. You're correct about the throttle, but regardless the Sprint Booster makes the car feel much more responsive. It also helps a lot with rev matching (the 987 nerfs the throttle when the clutch is pressed down). It is hands down one of the best upgrades I've done to my Cayman.

I have a PDK, so no clutch, and already find that the PDK is adjusting shift points based on speed of throttle change a bit more than I want sometimes. I actually am concentrating on moving the throttle a little less aggressively.

I get it, and that's what I thought as well. I simply got used to it, for the most part... so if you can adapt well, then it's not a huge deal. That said, it is easier with the gadget, as you get even more response from the setup than just your foot. That's why I have one, and it's a knockoff. I can't bring myself to paying for an expensive one.

What do you mean " you get even more response from the setup than just your foot. "?

SprintBooster has a video on this.. and the answer is - faster - no, sorry you can't. There is no physical connection in a drive by wire. That allows Porsche to determine the maximum speed at which the electronic throttle can open - it's probably determined for emissions reasons- and to avoid shock load on the driveline. That means the throttle opening (controlled by the computer) will lag behind the pedal movement. The SprintBooster eliminates that speed slowdown, so if you move the throttle faster the throttle opens faster and the car accelerates faster. That's the simple explanation - their website has a lot more about it. It has lots of other features (valet mode, anti-theft mode, race mode.. non of which I've ever used) that you may find of value. What is Sprint Booster - Sprint Booster USA Automobiles in the 21st century have replaced the more conventional throttle cable technology for an ECM (Electronic Control Module) that translates pedal travel into electronic signals in order to provide power to the wheels. The ETC system (Electronic Throttle Control) – also known as... www.sprintboosterusa.com FWIW - as far as I know SprintBooster isn't and never has been a sponsor here. The enthusiasm you see by owners who've experienced the difference isn't bogus, isn't prompted, isn't rewarded - they're genuinely seriously enthusiastic. That says something. If you care not to believe it - no problem - but I'd suggest seeking out someone who has one and will let you drive their car. My WAG - next day you'll be ordering one. YMMV - but probably not.

From an owner of Sprint Booster , I can vouch for all the positive reviews, but as Don said, find someone who has one installed and drive their car and you will find out for yourself the pleasure it will give you. This video demonstrates the operation and gives a visual understanding of how it does what it claims to do.

Interesting. Wonder how it well the throttle to open faster? I assume the peddle is sending position to the ECU and the interpretation is happening there, but apparently not. The peddle must have more electronics than I assumed.

I recommend people use the quote function so that the poster gets notification that someone is asking them a question... Anyway, my point is that when I blip the PEDAL (pedantic!) with my foot on the OEM setup, I was getting a decent amount of response... again, something I was getting used to on the car, and worked reasonably well. However, after installing the kSB (knockoff-SB), I get even faster "total response" because the electronics can move faster than my foot can. This makes sense, since electronics can do things faster than pure physical motion. With that, I find the blips I generate are faster, overall, and more satisfying. Again, this is a "feel" thing more than anything else, but I do appreciate it (both from an enjoyment perspective and from an "I can feel/appreciate the difference"... As for your second post, yes the pedal has more electronics than just a translation. There is a decent explanation here about how they work, overall: What does a throttle response controller? I think they do more than that, actually... I think they overshoot the position and then bring you back to it, so that your actual throttle position it's affected as much, but I haven't tested it electrically to find out. But that's what I do with my foot - for example, with the OEM setup, I would intentionally drop the pedal faster and further than I actually wanted, so that the TB would open faster, and then I would back off to the position I actually want for throttle. I've been doing this for decades, so it's second nature for me, and was very useful for forcing downshifts on automatic trans cars I had in the past. This way, I could force the auto-car to be in the gear I wanted, instead of waiting for it to figure out I was getting ready to pass. The same behavior helps a manual trans (my car) open the TB faster. But now, with the kSB I don't have to do it as much or as fast if I don't want to... and that's what I meant with my original statement above... For the more technically inclined, this is something engineers deal with all the time in PID systems. Basically, I'm using a human-based PID overshoot technique to get to the desired setpoint faster. The ideal of which would look like this (ignore the text): I believe this is what these controllers are really doing. And it's what I do with my foot, to varying degrees depending on the car I am driving. Without that sharp slope at the start, you will take longer to get to the desired setpoint, and that's what we are trying to get to faster... that's all. Again, this is what I BELIEVE the controllers do. And, of course, they can do it faster than your foot can... and more consistently.

This is why I refer to the video as the best explanation for what happens when you stomp the pedal. There is no linear connection for how fast or how hard you stomp the gas pedal, the built in delay negates that. Doesn’t matter how fast your reflexes are, the throttle body will only open at the predetermined speed. The demonstration shown in the video gives the best indication of the slowed down response without the Sprint Booster , and how the SB overrides that delay, making the response to the input from your foot more linear.

@WTFChuck - excellent and concise explanation. People might question why the manufacturer puts the delay and speed of opening factor into the stock pedal. I can think of several reasons: Driveline reliability and shock loading - way back when I was a younger pup I owned a number of BMW M3's. Each of those came with something called the CDV - "clutch delay valve" - which was a restriction in the hydraulic line to the clutch slave cylinder. There were lots of theories about why BMW would do such a thing since it actually limited performance. If you tried to release the clutch quickly and give the car power, the clutch wouldn't engage quickly, it would slip. This also was not found on European models of the M3's. Luckily it was easy to bypass, you just removed the restrictor from the line (it screwed in - male/female where the rubber hydraulic line went to the slave cylinder.) The real reason BMW put the CDV on the cars became evident when M3's (and Z3M cars) started ripping out the rear differential mounting points. This almost never happened on their automatic trans M cars, but was common enough on the stick shifts that kits were made to repair the damage (or prevent it) - and these were costly fixes. What was happening? People were dumping their clutches in the US quickly, causing shock/torque loading on the sheet metal used to mount the transmissions - and the CDV more or less prevented (or lessened) that damage. I suspect Porsche to some extent looks at the throttle delay response along the same lines - prevent shock damage to the driveline and mounting points. Emissions - I can't say with certainty that emissions has a hand in implementing a throttle speed control, but I can see if the emissions system (sensors, adaptations, timing, mixture and catalytic converter adaptations to throttle positions (and mixture) isn't fast enough - slowing it down might help the emissions system meet mandated requirements. I think that's a reasonable guess based on what Porsche did with the 981 "Sport-Plus" capabilities. Traction control and safety systems - Traction control, and the related 4 wheel braking stability systems will have an easier time of performing their function if the movement of the throttle in relation to the foot pedal is slowed down. That's three reasons I can think of.. there are likely more.

The Sport and Sport Chrono only works if your have PASM though, is that not correct?

That is NOT correct.

Okay cool. Then what exactly does it do? I have Sport Chrono in my 997.2 with a PDK and it adjusts the shocks, shift points, and can enable launch control when you hit the button (s).

Indeed it does all the same (and a bit more actually) on a 987, particularly if the 987 is a .2 car with PDK. It wakes it up. But you don't need to have PASM to have Sport/Sport-Plus. Anything you don't have (like PASM, PDK, PSE) it ignores and just does what it can with what it's got. I believe on the manual transmissions it adds RPM shift-matching on downshifts (but I could be dreaming that..)

Thank you so much for posting this. Having two previous manual shift Boxsters I was a bit under whelmed by the shifting of my PDK Cayman. ! I have been shopping for manual just based on the shifting on the Cayman. Its great in manual mode, but why have PDK if your just going to shift manually. I have now contacted 3 major Porsche dealers in the Pacific NW to get price quotes for retro sport installation. You are very correct in they did not know how to quote me a price for full purchase and work or just work (if I bought from Suncoast). I really had to explain, and give part numbers, for I wanted to purchase and install. Two of the three stated they needed to get back to me as they did not have an answer. The third quoted $10,000. LOL. After explaining to the third one in greater detail she too said she would have to get back to me. I have also contacted two indy shops (not sure they can do the work with contact to Germany is essential). Nothing back from them so far. I will keep this post updated as I definitely plan on having the upgrade installed if I can get a reasonable price and have confidence they know how to do the work. I was told the part number you listed above was for manual versions and the PDK is 02 not 01 as last numbers. I could not get or find the part number for the button cluster as it will be sport and sport+ for my PDK. I really hope this is a "thing" as it would transform my driving experience. I cant believe Porsche has programmed the PDK to shift so early stock. Another complication (I thought anyway) was that I have a softonic tune) but Scott at softonic has been very helpful. The "unlocking" of the sport and sport+ should not effect my ECM tune. Its nothing crazy, just removal of check engine light (as I removed secondary cats and custom exhaust). Any other helpful information on this retrofit would be much appreciated.

It's interesting that some dealers are so clueless about this. You might ask to talk to their shop foreman who will likely be highly certified with tenure as a Porsche tech and would remember back when our cars were new. What I did was I ordered my sport mode directly from the parts department and asked them to order me the proper switch. ECG Performance has a pretty complete list here of all the button combinations and part numbers: I have a new project brewing that will explore some of this again - installing the PSE. I'll be documenting the install and wiring up of yet another console switch

I know right?? thanks for the switch part # I believe the appropriate one is included in the Suncoast order. Well first real quote back today. $2565+ tax. I asked for a break down and its as follows. $1677.11 parts, $784 labor $65 misc ship charge. I was hoping for a bit more competitive pricing as this is the closest dealer to me. Lets see what the other two come up with.

Is the Software load considered a "Part"?

Yep, its the price to allow dealer to "unlock" sport and sport plus. I found out the correct part number for PDK trans is 997-044-903-02 the -01 is for manual trans.

So . . . . Seems the Sport/Sport+ Switch is about $100 more than the Sport only switch. Anyone care to chime in on the value for a 987.2 Base PDK car (No valved exhaust , No PASM )

Second, not so real, quote back today. After getting pretty specific with them and giving them the part number here is what the quote was. Retrofitting sports exhaust system, retrofitting switch console with sports exhaust. labor $3,100, parts $1756, Fees $150 Tax $505 so $5511 for adding sports exhaust....LoL. They apologized and are now working on correct quote.....I hope. If I had a dealer closer I would just stop by, but its a bit too far to just help them get me the correct quote.

Best prices on the parts sems to be at my favorite dealer, Delaware Porsche in Newark DE. Waiting on a services quote form them for the install. Would normally do the switch es myself and only have the dealer do the SW update, but being as I have to drive up there and will probably be on a bit of a tight timeline, they will probably get to go both. ( Well, unless their switch install is outrageous, then I will take tools with me and pick up the switch to install and take the car back the next day to do the SW update. At least there are no taxes or shipping charges that way, and maybe they even have a PCA discount.

Thats awesome, please let me know how it goes for you. I would do the switches myself too, but like you its a drive foe me and if they install they will support if anything goes wrong. Good luck

Part Number Part Name Price Quantity Total 997-044-903-02 Software Sport $1,254.93 1 $1,254.93 997-613-561-01-A05 Switch Matt Black $216.75 1 $216.75 Subtotal: $1,471.68 They said they would call with the install quote since those come from the service department not the parts department.

I've got the feeling you're not a spring chicken... so I gotta ask you - what'cha gonna spend it on in the next life? Or who will spend it when you're gone on what frivolity they want? If your 987.2 is a PDK just do it. It will put a smile on your face every time you press the button. Not a PDK - less questionable value to me. A pedal commander type throttle enhancer might be just the ticket in that case and about $1200 cheaper. Have you ever seen anyone post here how they hated that the spent the money on one? Certainly not anyone with a PDK-equipped car.

Afternoon all, Well second correct bid in....OMG how can it be so different from Porsche Dealers? part 997-0440903-02 Software Sport $2001.49 part 997-613-561-01-A01 Switch matt black $376.84 labor $1200

I agree and I will definitely do it , but just seems like throwing money away to not shop around......not to mention how hard its been getting them to quote the right parts. Also trying to get some level of confidence they know what they are doing. I find it a bit sad that I have to give them the part numbers and explain how they need to install it and what the result should be. Two more bids to come in but it looks like East Coast prices are much more reasonable them West Coast.

It is interesting that parts are based on location. I asked a parts manager about the differences (NJ tends toward 20% higher than DE for instance, DE has always been low for any foreign parts) - and it's based on expenses. They are allowed a certain profit above cost (MSRP). If their cost to carry an item is more than the same item in another locattion - they get to make the same precentage of profit above cost. That pretty much puts to bed competitive factors for business profit schemes. It seems a pretty simple sort of correlation between average income and cost of parts, explaining why parts are so much more expensive in NY than in FL.. but it seems there are always outliers. I haven't seen any discount parts dealership offers from dealers in Mississippi or Louisiana.

Here's the exact charges for my Sport Mode install December of 2024 at Porsche of Nashville. I consider my local dealer to be in the most expensive category, but they do give us up to $175 off any service if you're a PCA member. I just spot checked the prices on another dealer's website and they haven't fluctuated much. INSTALLED SPORT MODE BUTTON AND PROGRAMMED $483.88 997-044-903-01 SOFTWARE SPORT $902.42 997-613-543-01-A05 SWITCH MATTE BLACK $125.26 Out the door = $1493.05

Man I live on the wrong coast for Porsche work. Still waiting on two more quotes but so far the best is still over a $1000 more then yours. Hey maybe a $1000 worth of fuel road trip

If you're going to travel for it, I wouldn't go any further than Harper Porsche in Knoxville. Great dealer who is "on board" with competitive online part prices. Kill 2 birds with one stone and drive over for their Platica show in May and have your sport mode installed too.

Seems the jump in price happened sometime last year. The real variable seems to be the labor. I guess i will have to call them back to get my quote.

So chiming in here as I'm also looking to do the same on my 09 BS with PDK , no PASM , no PSE . I sourced the switch panel from Gaudin Porsche in LV for ~$210, installed in 5 minutes myself. I reached out to two local dealers, both said they charge 1.5-2h programming time which is $700-800 (SF Bay Area) and they charge around $1500 for the code. I tried circumventing this by sourcing PCM activation codes from a shop in albania, which includes a code for Sport Chrono. Then I took it to my indy shop for programming and they said the code was not accepted by either their piwis 2 or piwis 3 tools, so maybe it's the wrong code. Note that I also have an aftermarket head unit installed, but the tech mentioned he doesn't believe that is the root cause. I'm currently researching my other options aside from biting the bullet and buying the code from Porsche for $1200 minimum The change in parts pricing happened around Nov last year, I had been talking to some out of state dealers for parts number confirmation and they did mention a price hike.

@mhwang sorry that code didn’t work out. Another poster said this and I think he is correct - adding sport mode modifies either the emissions or fuel economy (or both) therefore Porsche tightly controls these installs. They could be limited in how many they allow. It’s the best theory I’ve heard so far. At least your local dealers are willing to install it with a switch you bought from somewhere else. Are you a PCA member? Ask them if they offer PCA a parts and service discount. I also noticed pricing going up on some parts too. Tariff related?

You might be referring to one of my posts. I had some experience with a SW upgrade sold by another vehicle manufacturer. The critical issue was that they have to support their Corporate average fuel economy and corporate average emission requirement data they provide to the government. So if you make enough really clean and really efficient cars, you can sell a few power hungry and polluting monsters (Taking it to the extremes, but other limitations come into play.)

PCA member, one of the local dealers here does offer 10% PCA discount, but it's still more expensive than ordering off one of the online parts sites like gaudin or delaware. And my indy labor rate is quite a bit cheaper - they've done it before with the dealer codes, so I imagine if I just do the normal thing, the rest is straightforward... My last attempt is with a local forum member who has a 3rd party tool with similar capability to piwis and is curious just how much it can actually do. If that doesn't work, I will either scrap the project or bite the bullet for the code.

Im definitely interested in how your doing. Im still waiting for one more quote and a little nicer weather.

Well, i have a trip to DE coming up, so I'll get the buttons ordered. Wondering if I should pick up the code for another dealer to install, or am I risking it not working, or the dealer refusing to install it?

FWIW I emailed Suncoast if i could just get the code - they replied saying the switch must be ordered with the code otherwise Porsche hq will not approve the request...this did not come up with the 2 local dealers when I asked

So then on to the second question. If I get the switch and code from Delaware (great price and no tax) can I have another dealer install the SW after I do the switch? Or do I have to plan a second trip to DE with the Cayman?

I wanted to document my experience installing this as there's not a lot of info about the Sport Mode procedure and process. I decided to do this because I recently test drove a Boxster GTS 4.0 and am trying to talk myself out of buying a newer car, and modding my 2010 Boxster base is a lot cheaper. And since I have a base Boxster , I always thought it would be cool to have one with all the options, kinda like if they ever made a 987.2 Boxster T . And finally general curiosity, would I even notice the sport mode or not? The dealer warned me it's not a lot of bang for the buck, but I assured them I understood that and would not return to complain. If you want to do this, your local dealer probably won't know much about it, and they probably haven't done this in over 10 years anyways. Depending on your service advisor, you may want to go straight to the parts counter. The software is part number 997-044-903-01 (for a manual transmission). This is literally a piece of paper in a poly bag with a part number sticker on it. Looks something like this: The reason I went through my local dealer and didn't order this from another online dealer is due to how this mode is activated. The software update is associated with the vehicle's VIN, which you need to provide when purchasing the above part number. Your VIN gets registered with PAG who provides a code to your VIN that the tech inputs on PIWIS to activate. Simply installing the button will not work. Even though I knew my local dealer would be more expensive, I didn't want to take the chance of ordering it from somewhere else and them telling me to go have it installed from where I ordered it from. After the piece of paper came in the parts department was not sure on which switch to order. If you look in the Porsche parts catalog for the 987's you'll see 20 different switches. The parts manager was able to find an old bulletin about this and found that I should order 997-613-543-01-A05 (with A05 signifying the color matte black, which is the only color available). When you look at the parts catalog, this switch has the following option codes: 029 - Standard Chassis 476 - PSM 480 - 6MT 639 - Sport Chrono (however my car was not equipped with Sport Chrono. I think in this case this just refers to the switch having a "Sport" button) 640 - Sport Chrono Plus (however my car was not equipped with Sport Chrono. I think in this case this just refers to the switch having a "Sport" button) The switch was ordered from Germany, and once it arrived I scheduled an appointment with a service advisor. They gave me the old switch to keep, and when I got in the car I hit the button and saw "Sport" in the meter cluster. Impressions: I did not have any issue taking off from a stop as I thought I might. Car feels more lively, making me think why they mapped the throttle input so slowly from the factory? Where I was pleasantly surprised is going into the throttle at mid range, like when you're in 4th gear and overtaking a slower car while staying in 4th. The car feels a lot more peppier in this range and this was where I thought ok, I like this a lot. I have tried some heel-toe downshifting and don't notice a huge gain but throttle is peppier so it should make this easier to do. I need more seat time practicing this to really exploit the changes. In total this came to about $1500. Is it worth it? I think for me it was, simply because I enjoy it and it makes my Boxster a little bit unique. My goal for this car was to put as little aftermarket on it as possible while still exploring the factory parts catalog to maximize enjoyment. Assuming I don't get bit by the upgrade car bug anytime soon, future plans are to add the PSE. I think PSE would work to where when I hit the Sport button both Sport Mode and PSE engage. I'm not 100% sure on this but I don't think PSE needs the same kind of secret code that Sport Mode did, and I can just activate it with Durametric. If anyone has the PSE instructions for a 987.2 I would love to see those!

The switch you got is considerably different from the one originally sold with Sport-Chrono . The original switch had two sport modes - "Sport" and "Sport-Plus"... My WAG is Porsche discontinued the Sport-Plus mode due to some emissions issues and fines they experienced with the 981 series Sport mode . They eventually neutered the "SportPlus" mode on the 981 if they got their hands on it (much to the dismay of many owners.) I wonder a bit if they backed off any with the Sport mode vs the earlier Sport mode or changed it any other way. Since you have stick shift - lots of what they list as added isn't available to you. Launch mode, race-track mode (I assume SportPlus). I imagine there is throttle remapping going on and it may bump the interference level of the PSM up a notch. An addition I've found wonderful (and great for the money) is the SprintBooster - which remaps the pedal/throttle relationship beyond what the Sport Chrono does. It doesn't require a dealer to install it, a competent DIYer can easily do it, as might any good independent shop. I don't believe the PSM is tied to the Sport button, but I've been known to be wrong. Perhaps someone with both can comment..

There were multiple button panels available on the 987. The one he got was for a manual car with the sport mode option (sport mode without sport plus). Sport mode on a manual remaps the throttle pedal to be more aggressive and increases the limits at which PSM engages. If you have sport exhaust it also triggers the PSE.

It's too bad that this can't be done via Durametric or even any of the alibaba PIWIS clones , as this seems to require an online connection to Porsche to change vehicle configurations

Equally, besides the panel that's replaced - the PIWIS efforts here take minutes, so find yourself an Indie that can do the coding rather than paying the dealer to do it or go aftermarket.

My 997.2 has sport mode and my 987.2 has had it done by the previous owner, and I'm not sure it would be worth the $1500 as it's way too sensitive on the road and I've really only used it for the track

From what I've learned I'm pretty sure an indy can't do it. Unlike most of the coding the Sport Mode add requires a dealer connection to Germany.

No kidding! I think I can turn on PSE with the Durametric and Foxwell though. Same what I researched too @gubi I just went for it, called it a Christmas present. I cringed because I know I could get the software and button cheaper at other dealers, but I've heard ours will not install parts not bought from them. At least they gave me $150 off for being a PCA member though.

Correct. It can only be done by a dealership hooked to Porsche computers in Stuttgart.

I had mine added many years ago, mine has sport and sport +, probably since its a PDK car, I do you sport + a lot since I track, really worth the cost.

I've only tried Sport-Plus a few times around the neighborhood and on a few local fun roads - it really should be called "track mode". It's fairly brilliant in what it does, both to the engine/transmission and to the PSM settings.. but around town - it's not really useable (going down a 25mph road with the transmission in 2nd gear and RPMs up around 4K - with my Fisker exhaust - isn't a friendly thing to do, so I end up manually shifting up to 3rd. Which is where the regular SPORT mode would have been..)

I can vouch for what deilenberger said about the SprintBooster . For far less than backdooring the complicated and costly addition of Sport mode in a car without it, it’s a simple, inexpensive an relatively easy DIY project to add the SprintBooster which gives you numerous options to remap your throttle response. My ‘08 Boxster has multiple personalities, switching from Sport to Race with 9 levels in each mode. And you get the added bonus of making your vehicle nearly ‘unstealable’. By utilizing the ‘Pedal Lock’ mode using a PIN code of your choice, it disables any input from the gas pedal. One can leave the car running, enter the Pedal Lock mode, and walk away from the vehicle. Anyone seizing the opportunity to drive away with a running, unlocked vehicle will quickly find that stepping on the gas pedal will have zero effect on the engine, rendering it unmoveable. The addition of this device has me smiling every time I drive it. Even though there is no addition of horsepower, it sure feels like it when the throttle response is enhanced.

1) Again, this is really awesome -- but I always wondered if basically this was simply the equivalent of a Sprint Booster or the like with only one (SPORT) or two (SPORT PLUS) settings. 2) Interesting that the Sport/Sport Plus software is apparently a dealer only thing. For the 981 , Sport Chrono codes can apparently be sourced if one knows where to look (I haven't done so for my 981 ); I figured this might be similarly simple that the PIWIS can enable -- assuming one enters in the generated code that is based on the car's VIN. The only thing I'm aware of that definitely requires a dealer's network is key programming. Who knows - I might mess around with this at some point -- but that would require a $125 gamble for the switch, $100 for the code, and my PCM might be required (which I sold on). ( @jjrichar - What do you think? ) 3) I'm thinking about finally trying a super-cheap Chinese knockoff of the these throttle modifiers (aka, 9-Drive) sometime soon, which sell anywhere from $60 or far less via AliExpress. The way these things work is apparently the same, where the accelerator sends out a signal to your car's computer -- and the booster goes in the middle and modifies the signal before the engine sees it. I figure given that it's a fast install... if it's absolute hot trash, I'd send it back if ordered on Amazon. Since the car purchase, I've thought about installing a Sprint Booster or the like, but have been put off on the price per what they deliver. Many people swear by them. The one thing I do know is that with any of these, apparently one has to be super-careful about driving in reverse, as that's when one wants a very gentle throttle and these are purchased for the opposite. Apparently, there may be more expensive models that take this into account. Do I feel mildly less at ease with a knockoff that will modify my throttle where something could go wrong? Absolutely. These have been around for years for all sorts of vehicles, and I think we'd be hearing about stuck throttle issues by now. What has come up is that some cars will throw codes with these, so YMMV. Meanwhile, I know that some models have a failsafe mode that will just revert to OEM if something goes wrong. All this being said, my hunch is that all of it is manufactured in China and it's a question of marketing and private labeling -- at a higher cost. Plus, odds are I'll find a setting that will work and would just leave it in that setting -- and ignore the fancy display over time. We'll see...

I've been using one of the knock-off 9-drive units for over 2 years now, works flawlessly and should be every 987 owners first purchase. Cheers, Julian

I think I should point out that the best application of the sport-chrono mod (Sport, SportPlus) is on PDK equipped cars. Switching it on completely changes the mapping of the PDK , and makes the car feel more responsive. I've been told it also backs off the limits on the PSM allowing for a bit more sliding around - but I normally don't drive the aggressively on public toads. I usually switch to Sport unless I'm stuck in traffic. SportPlus is radical enough that I don't use it - and don't anticipate using it since I won't be tracking my car, but people who do track their PDK have all been highly enthused about what it does for the car. If I had a 6 speed - I might think the SprintBooster was enough...,

Agreed, I have a knockoff as well. Don had a chance to drive it, and I had a chance to drive his car with the SB on it. I will say that the SB does seem to have a smoother response curve overall... but maybe that was just since his car is so much nicer than mine, overall! That said, I am very happy with my knockoff, and have no desire or need to get an SB . It works pretty well as-is, so I'm not sure I care that much. Fact is, I drive so many different vehicles and am a very adaptable person, in general... so I can easily learn and adapt to any car (or other things) very quickly. So while the knockoff might be different, I get used to it quickly. Honestly, I was used to the OEM tune, and would blip the throttle hard "naturally" myself. Again, I just got used to it... but I do like the knockoff and would recommend it, in general. I think this is the one I have: https://www.amazon.com/Throttle-Response-Controller-Accelerator-2002-2012/dp/B08RBW7BWB

I don't get these throttle gadgets. If I want the throttle faster or further, I can just move my foot further or faster.
