I just flashed my 996TT and I'm amazed at the gains! I just want to put a big THANK YOU out there to EPL and Dave, who is a great person to work with. I'm a very happy person. That really opened up my 996TT. All I have is the muffler bypass and run a toluene mix to get about 93 octane. We only have 91 here in AZ, so 1 1/2 gal of toluene and it's all set for the 93 octane tune. Everything went perfect with the tune, and with very impressive results. WOOHOO! Smooth as silk.

 

Amazing what a tune will do to a turbo car. Wait until you add the upgraded turbos, since it will only be a matter of time.
