Hello all, I have a 2016 991 turbo s cabriolet and just installed a stage 2 power package with Sam (SamboTT@bydesign).

Sam made the entire experience a breeze and would recommend this setup to anyone looking for adding more power and thrust without changing the car's refined character too much .

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

So I bought FVD 100 cell cats for my 996 C4S paired with headers and PSE. I also have the fab speed carbon comp. intake. I am about to buy the softronic tune if a tune is my only option. I have done softronic tunes on an 09 boxster S and my 07 cayman S so I'm familiar with it, but I've read there are some o2 options I might can look into.
Can I use o2 spacers to get my light out without a tune? If so, will it get rid of the roughness in the power band?
Has anyone done anything else to make the CEL go out without a tune? NO IM NOT GOING TO TAKE OUT THE BULB
Thanks in advance! I appreciate any advice.
Hello all, I have a 2016 991 turbo s cabriolet and just installed a stage 2 power package with Sam (SamboTT@bydesign). picked up the car today
Installed equipment:
Cobb Accessport Stage 2 program
Kline innovation 70 mmsport exhaust with 100cell cats
IPD plenum
BMC filter
Kline Inconel headers
This is the first Porsche I've modified and am very happy with the result.
The car is extremely responsive with noticeably less lag and tremendous torque- plus it's very close to stock at idle with a more pronounced intake sound at full throttle. Acceleration is instant and passing power over 60 mph is where the extra power is really felt (as stock is pretty quick off the line as it is). Sam made the entire experience a breeze and would recommend this setup to anyone looking for adding more power and thrust without changing the car's refined character too much .
I have seen some on this forums describing the car as dull in stock form and I can see where they are coming from, and this set of modifications definitely makes the car anything but dull.
Before you do anything, pull the codes that are causing your CEL and use that information to understand what is actually wrong. CELs get thrown for many reasons, only a few of which may be due to your cats.
Many auto parts chains will read your codes for you for free, or you can buy a Durametric and do it yourself.
Hello- that's the next step- Data collection. I'm curious as well . I will contact Sam and plan to meet to collect some data regarding 0-60, 1/4 mile time and hp and torque gains. Sam took some short video clips of exhaust while revving and of the car passing by -so you can get an idea what it sounds like. I'll ask him to post it and I'll post that data once it's collected.
Yeah, he's right. Go ahead and get the codes and post them here, we'll help. I doubt the roughness is caused by the cats, could be missing or a vacume leak.

Only code showing is insufficient catalyst. I ran the codes first. It's only rough occasionally like its getting a bit rich. I assumed it was the cats fault.
I did install 997 coil packs and all new plugs while I had the headers off too.
Hey guys.
K, it was a pleasure to meet you and work with you. So glad we were able to make this transformation. Having the collection and history of cars that you have had tells me you know what you are looking for. Guys he has had every iteration of 911 Turbo since the 993 and even has a GT2RS. Then he's got the other side of the spectrum with amazing Ferraris and the sounds they make. I think we were able to give this car little bit of flavor from all of those.
We will get some more videos as soon as Los Angeles conditions permit.

Are you sure about that? I thought they were just plain jane like any others. The alternative would be to just get some generic cheapos off eBay as most are just extended tubing or piping to move the O2 sensor away from the direct stream of the exhaust gasses. They both come in straight and L configurations for tight spots.
But honestly, I would spring for the ECU upgrade as you'll get back some of the low end power and torque that is often moved from having a cat bypass or high performance cats. Not only can you defeat the CEL light, you will most likely also get the throttle response remapped to provide better throttle response as well(eGas models).
I'm working with a vendor right now that is similiar to Softronics way of programming(programming at home through OBD without having to send in your ECU) at a fraction of the price. This vendor will also modify my map for free if needed after I take it to a dyno and if the AF's are off in anyway. Stay tuned...
That's what I said Chris!

Right off the site:
this is not your usual 02 sensor spacer that pushes the 02 sensor away from the exhaust stream, this 02 sensor CEL fix actually uses a tri-metal substrate that is
platinum/rhodium/palladium coating that works just like a real catalytic converter

Awesome. I love competition in the tuning arena. The customers win. Competition always pushes people to do better.
Yes you need pictures of someone revving the crap out of that exhaust like I put up recently when I did that to my Europipe
Quote:
Yeah personally I would rather go the proven electronic route and get a my ECU modified and also get better throttle response and improved HP to boot.
By the time you get these since you have to get 4, you're gonna be at $200-260+ depending on configuration. IIRC generic ebay ones can be had for 1/10th the cost so the risk will be less if these don't work out. OP already has cel100 so he maybe able to get away with adding the generic ones. my $.02

Great video. Tons of crackling and popping when you lift off the gas. Tone of exhaust is definitely higher pitched than Europipe. This should sell well.
Hi Im new to this forum but know the OP well, he referred me over to Sam
I have a fairly new 2015 Turbo S cab and will be doing a similar mod by
Sam (SamboTT@bydesign).
Planning:
Cobb Accessport Stage 2 program
Kline innovation 70 mmsport exhaust with 100cell cats
IPD plenum
BMC filter
Kline Inconel headers
Y pipe
Intercooler
I sure wish they had an E85 tune like my GTR, I too have a full stable of exotics (about 13) including 918 Spyder #130, 2008 GT2, 2014 GT3, 1997 993 TT and 2015 TTS cab (which Sam is working on soon) I also have a 2014 Black Ed GTR with Stage 3, Visconti E85 Flex Fuel (pulling 769hp to the crank on Mustang Dyno), plus 2015 GTR NISMO, 2 Ford GT's, Lamborghini Huracan and Countach, 2014 Shelby GT 500, 2007 Hummer H2 SUT
I know I've lost my mind and the car "bug" has consumed my mind, but I dont care. I will let you guys know how it goes and keep you posted with pics on the 2015 Turbo S mod. I sent Sam the deposit of $1000 today, I have spent a lot of time in the GTR world talking to many tuners both at Cobb and ECUtek and I can tell you Sam totally knows Porsche and what he is talking about, can't wait to see the results!!!
You only need 2 spacers....the ebay SS one's are great and cheap....
spill the beans alpine...i'm not too fond of my current tune that I've had for a few years...
