So, From doing some reading/research, if I were to go turbo I would have to program the ECM in regards to allowing the changes. Also the same for doing any not so major but major enough changes. Who knows what is a good program for an 05 Pontiac Sunfire with a 2.2l Ecotec motor, what parameters I would be looking for to change anything basic to start, and any other information that can be provided? I'm planning on putting a larger TB on, a CAI on, 2.5 hi flow exhaust all the way back, and in the future a turbo charger.

I need an adultier adult.
