The COBB Accessport is the best OEM ECU tuning solution. We've got plenty of these sold and I even have a used one for sale right now ready to go.
The ProTune solution will also take the car to the next level and is a service offered by us as well.

My favorite analogy goes like this. The OTS maps the COBB Accessport provides is like getting a suit from the suit store. It's going to look nice, fit well, and do the job.
However, a ProTune is like getting the suit tailored. It's going to fit the contours of your body, sized perfectly at the waist, just like the tune will be optimized exactly how the car is behaving and extract even more out of it. It's going to be sharp

PM me if you have any questions. The PDK is a wonderful touch as well.

I wouldn't. Do you really find yourself wanting more power in turbo car?

Your warranty is gone if you decide to do it. Don't buy all the nonsense posted 'its the law they have to to prove it.' If your car has CEL or something quirky that requires sending data dump to Porsche tech line (very probable as dealer techs just follow instructions), they will see ECU has been tampered with even if you turn to stock (history missing and it wont even be your original stock... a 'CODD stock'), they will refuse to look into it. At that point you're not going to be able to fight the Porsche corporation and dealership in court even if you might win.

JB4 is untraceable when disconnected

Unlike flash tuning like COBB.

You're certainly entitled to your opinion but thousands of owners of just about every make and model disagree with you. That's why there are literly hundreds of aftermarket manufacturers making parts and systems to change the stock system. As stated above the factory can't deny a claim of the failure of any system unrelated to whatever modifications were made.

More than opinion... personal experience.

Install Cobb tune, get a CEL, then go to the dealer saying your PDK is in limp mode sometimes and see what happens. Also tell them to look into why engine running lean with aftermarket cats. You cry all you want that they must prove the aftermarket parts caused it...that thousands of people are using them. They wont care and will explain why there mod might be causing it...doesn't matter if what they say is true or not.

I agree...there's a large market for aftermarket stuff and people who buy it all the time. Plenty of people who mess up stock designs. Yep... lots of stuff happens in the world. Someone is probably eating rice in China, but that doesn't mean its good food.

Have not had this type of negative dealer experience. My dealer is selling and installing Cobb for customers. I have tuned 3 Porsche TT cars including my current TTS. The car just behaves better than stock. I'm not looking for 700-800 hp just a sharper PDK response a little more giddy up with better vocals. The Cobb and Europipe do both without making the car difficult in any way.
I know tuning is not for everyone and I would consider myself "tuner light". But there is personalties in the car that need to be expressed that stock does not allow.

Did not dyno mine, have seen another one dynoed where it lost 5whp which is neither here nor there, the advertised gains are minute even if achieved. I've tried the stage 1 cobb files on at least 2 other platforms, same results.

Hmm. When I installed the COBB Stage 1 on my stock TTS, it had a pronounced gain in torque (*** dyno confirmed). I'm stage 2 now with a catless Klline, and it traps 129 in poor DA, while spinning hard all the way through 2nd gear (11.1 et., 1.87 60 ft.)

The OTS maps are a start, but a custom tune is needed to gain performance. I've used Cobb on multiple turbo's, including protune and accomplished good numbers. It also depends on what dyno is used.

arkadyzv

The question was in regards to Stage 1 tune. Your results with the stage 2 tune effectively means its slower than stock, the increasing traps is from spin and poor 1.87 foot. Also IMO the easiest way to measure horse power or performance increase would be to do a 60-130 one stock and then modified. It removes the traction out of the equation. Mine ran the same 11.1 on the street bone stock on the crappy stock pirellis, just switching to the michelin ps4's got it back down to 10.7 , 10.8 with much improved 0-60.

The cobb advertised gains are a measly 3.5 hp and 25tq crank, everyones butt dyno is different so I'm not arguing that what I felt is different than what you feel, feel is feel . But my opinion is that overall placebo affect aside the car is not any faster than stock and to spend 2000 on a cobb to just run the stage 1 file is a waste of money. I felt the torque hit on mine and then I felt the timing pull up top. I got it protuned days after, these cars do adapt, maybe it improved with more driving. Something as little as 10wtq in a car that makes 500wtq or so stock isnt something I consider a quantifiable difference . The OTS maps are designed to work in every climate, elevation, DA, ect some might have better results than others but 60-130 I doubt the car is any faster where just stock and protuned it would be at least a few tenths faster.
