I just bought my 04' x-cab, Z71 last week and already done a few mods to it. Next week the 5" Pro Comp lift goes on as well as the upgraded stereo system. I know I will need to get the truck tuned somehow after the lift. I am going with LS1 edit since I had it on my C5 and was very happy with it.
So that said...what are some basic mods that are done to these trucks? I was thinking of a K&N replacement filter for starters. Does anyone know the P/N for this?? What about the IAT sensor relocation? Does that do anything? I don't want to put on an aftermarket exhaust or headers. I just want to do the "freebie" mods if possible. Thanks! I just ran into this site today and it seems to be pretty cool!!
