Installed a tuned PCM I had done for my 02 anniversary which deleted the rear o2 and egr codes plus some timing and fan turn on etc.
Car runs really well and the check engine light is no longer on BUT I no longer have performance shift. The button does nothing.
Is that because it isn't tuned to be a 2000 with the performance shift option??
01+ Gp's did not have a performance shift button, so the performance shift would not have been "turned on" in the pcm tune for your 02 Anniversary car.
