Softronic, Factory Sport Mode Or Sprint Booster?

Hello, I have a 2007 cayman s I’m tempted to pull the trigger on softronic since there’s a nice holiday discount right now. I’ve read up on all 3 options I still can’t make a decision so I’ve been putting off doing anything. Overall which would bring the most value and performance?

The Softronic tune is the only option that will raise HP and performance. Sport modes and sprint boosters have zero impact on actual car power. Both are just a throttle remapping that condenses a normal linear 0-100% throttle down into a smaller travel range so you are actually applying more throttle that you normally would for the same pedal position. Sport headers and a tune are the two biggest bang for the buck upgrades for these cars if an increase in power is desired.

As stated, the Sprint Booster and sport mode both just remap the throttle pedal. It is correct that they add zero power or actual performance. That said, they make the car feel a LOT more responsive, and the Sprint Booster is pretty much the best upgrade I made to my 2010 CS. If you've got a manual it also makes rev matching much easier.

Sport mode ( Sport Chrono ) does more than just a throttle remap. It also widens the slip angle before TC kicks in (so you can get the rear out a bit more). Also, if you have PASM , sport mode firms up the suspension into sport mode as well. If it were my money, I would get the Softronics tune and Sport Mode.

Softronic with plenum and throttle body is $2300 before install, and that combo gets you a (claimed) 25HP. That's less than a 10% improvement over stock. Generally speaking, chiptuning normally aspirated cars just isn't worth it. Sport mode is $900, again before install, which requires a dealer. Sprint Booster right now is $230. It installs easily, and if you don't like it you can always pull it out and sell it.

I simply installed Softronic software at about $ 1,200 and got a tremendous boost in low-end torque. I haven’t dynoed it, but have about a 2-second improvement in lap times to show for my investment, in which I am, needless to say, well-pleased. “Worth it” is a relative term, I reckon.

The factory Sport-mode and the Sprint Booster are a waste of time if you are looking for increased power... neither will delivery it. I've run APR and Evolution Motorsports software on my 2008 Boxster S. The APR was okay, but you could tell it was conservative and although it was a 91 octane tune, it was never really happy here in California. The EvoMS software has been amazing. I have two different tunes... Stage 2 and now the RS370 kit. While I typically agree tuning a naturally aspirated car is pointless, Porsche left a lot on the table with the M97 engines. The EvoMS RS370 kit requires other upgrades in addition to the software, but it's safe to say the car makes every bit of 370 horsepower. I have a friend with a 2019 911 Carrera T and we're about even in terms of straight-line performance. The best part is the car is happy on California's crappy 91-octance fuel. A lot of tuners promote power gains, but you should be looking for a company that provides solid drive-ability of the car after the software upgrade. The car should feel like it did from the factory, just with more power. Without a doubt I can tell you the EvoMS software drives like stock. There's no power peaks or valleys, no throttle-hang when you let out of the throttle or any other strange behavior. I would do it all over again and if I'm ever lucky enough to buy another Porsche , I'll be hitting up EvoMS for software on that one too.

I understand that the Evolution Motorsports modifications do not have CARB certification, but have you passed smog in California with this setup?

I recently bought a Softronic flash and Soul long tube catless headers for my 2007 987.1 S. Scott at Softronics and John at Soul really did a nice job connecting the dots. My car also has a Porsche GT3 Plumen and 78 mm throttle body from Scott as well. His flash tied all of these parts together to provide a smooth delivery of power from 2000 to 7000 rpm. There is no flat spot any longer around 35-4500 rpm, just an excited motor producing a few more hp and torque. Although the 78 throttle body is slightly smaller than the newer 82 mm GT3 throttle body, this smaller throttle body is well suited for my 3.4 motor, rather than a 3.8 of the newer GT3's. Scott says the throttle body volume difference only occurs above 6000 rpm and less effective below 5000 where I really need all the torque I can get. I routinely shift at 6800 to save my motor. This completes the Softronic Cayman Power Plus Plumen Race Kit along with the EVOMS air intake kit. I asked both Scott and John to provide a product that would act closely to the Sprint Booster, but making more power along the way. Scott assured me that I would notice the power difference in drivability with this combination of intake, Flash and exhaust. He customized the Race flash to include 93 octane fuel delivery map, more aggressive ignition map, retuning the remaining intake resonance valve and retuning the Vario Cam Plus. This massive file downloads within minutes. The result is a very smooth power delivery from idle to 7000 rpm.

How do you like the Soul headers ? Is the fit/finish nice? Do you have any clearance issues? What exhaust are you running in conjunction with the headers ? I have a set of Racing Dynamics short-tube headers , but I’m interested in switching to the Soul headers with high-flow-cats in an effort to reduce the smell and sound output (my car is ridiculously loud at full-throttle).

I am using a Milltek stainless muffler and tip extensions connected to Soul long tube catless headers . I keep those mufflers polished so you can see them through the air exhaust vents in the bumper. Surprisingly, I do not smell a lot of exhaust on startup or when standing in the back of my car while idling. My car burns almost no oil between 3500 miles changes which is coming up soon. So, no blue or white smoke at startup. With Scott/Softronics massive ECU updated race file, my car really runs nicely. The O2 sensors are turned off by the file. Scott also sent me an OEM file with the cats turned on and I have saved the old catted manifold, which did pass the State of Washington DEQ plugin test last year. The State has eliminated this whole department as a money saver, so those 20% zip codes that were impacted can now drive without inspections. I have a LN skid plate under my 2 Qt sump and was concerned about clearance to the front header pipe, but on install had plenty of room. The headers bolted up to my existing exhaust perfectly. I just had some suspension and engine water/oil heat exchanger work at Cantrell MotorSports. Their alignment specialist told me that my exhaust setup was the best sounding Cayman he has heard- At least his endorsement was not negative. The Soul headers are a piece of art. The tubes are quite thick, which I believe affects the sound, especially above 4000 rpm. No drone to speak of at any rpm. Thanks.
