I am looking to up the performance of my 2002 Avalanche some. Im not looking to go crazy. I have a 600HP camaro and a 2001 Hayabusa.... i have all the "speed" i need from them. The truck is more of a chore/house/camping vehicle. I dont need it to do 11's. I am looking to do intake/exhaust just to free it up some, but i was also wondering if anyone knew of a tuner in AZ to get a tune done. Like to gain some HP but maybe some MPG too (i know.. its 1 or the other )
