Performance parts/upgrades for 2500HD
Ok, now I am sure that someone has already asked this question and received answers but there are over 250 pages of threads and I don't want to spend my Saturday looking through them all when football is on. Anyways, I own a 2003 Chevy Silverado 2500HD with the 6.0L Vortec V8, a pretty powerful engine in my opinion, I have no problem getting it to go 90mph+ with 35" tires and being lifted. The only modification is a cold air intake, only a 5-10HP increase. I have already lined up some parts such as a fuel catalyst, bigger fuel injectors, performance fuel rail, performance headers, and cat back exhaust which can add another 15-30HP together, I am wondering what else I can buy to increase the HP and Torque? I don't have unlimited funds either, so I'm not looking into buying a turbo for the truck and I personally don't have much faith in those "chips" and don't want to waste any money if I can help it, any suggestions as to how to get more HP would be appreciated.

honestly the programmers do help alot, also depending on what chip you get. youll get about 30 max hp outta a chip but you can also adjust many things to what you like. just a suggestion. diablo and edge programmers are great for gas applications

i would go with cat back, headers, CAI, custom tune. larger injectors will not help unless you have the internal mods, heads/cam swap or a blower. the fuel catalyst, performance fuel rail, IMO. is a wast of money. with 35'' tires you can look into going with 4.56 gears..
good luck..
