2004 chevy performance upgrades
Ok just got the truck. specs are 5.3 liter, 2wd, 3.73 locker, regular cab. So waht are the first mods that should be made. I would like to make it as fast as possible with out tearing into the engine and without supercharging. Money is tight and the truck only has 200 miles on it. Any help would be great, prices also help. thanx

I have the same questions as I'm just getting a new '04 Z71.
What I wanted to know is, Will '03 parts work on an '04?

well first I will do a exhaust and I guess then comes the tune and then when I get the money the headers. I would also like a CAI and a few other things to up the pony's.
