Thread: Please help Performance shift

Thats what i would do.

Well there's only 2 tables in the pcm that really turn it on, so if you can see those tables and changed them, you should be set on that end. Either that or try a different bin file for your GT.

Next is to double-check the wiring on it, if you feel confident you changed those 2 tables in the pcm, it's time to re-do or have another pair of eyes check your wiring.
