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

 

Headers / Exhaust and a tune.

 

how much is it to get headers installed?

 

save the money, and do it right.

do it yourself, its alot easier than it looks. takes about 4 hrs.

 

Put some 411 gears in.

 

I did cold air intake first.I have AEM brute force cold air intake.I had 150 miles on the truck when i put it on.But,there might be something better to do first.

 

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?

 

another vote for a tune, makes an awesome improvement

 

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.

 

where is the list or tech on free mods. I would like to do these first if it help.
