Hey Cliff! Cheers! I made an intro post to hopefully find all my old friends.

vt, the .2 on all versions started in 2017 cold is right. The S is all new and the non-S is very similar to the .1 S but still has new features and computer.

 

I have a 2015 TT that is stock except for a Sharkwerks exhaust. What numbers could I expect with a Cobb tune and 91 octane (all that's readily available here)? Any downsides? Will I run into overheating or other issues running it on a track?

 

Just one nice feature about the AP is that you can receive it with all maps up to stage 3 loaded! So you can run Stage 1 (set up for factory cats/exhaust) and be fine. On the non S you will gain more and the results are the same as an S. You can expect up to 60hp and and 100tq. You will leave and get several Maps for different fuels and octane levels so everything is safe and properly calibrated. Everyone I have dealt with loves their Cobb. Feel free to reach out for more details. I would gladly offer you a trial and get one to you next day!

 

Couldn't have said it better myself Sam

If you can use a COBB Accessport for your vehicle, don't think twice about it. We prefer to supply COBB Accessports/Protunes wherever possible for our clients due to the flexibility of use and various perks you don't get with a standard ECU flash
