ok guys, I know gm was doing funny things changing pcms and whatnot during this time of 05-07...
so what i'm wondering for one, can i tune this vehicle? ( I believe I cannot from what i have read)
2nd question, Can I swap in a 2007 PCM from the exact make/model car and is the pinout the same?
if so, where can i buy a 2007 PCM from? just gm direct?
