Alright fellas what do ya'll think I should gain off of my upgrades. Right now I have a 5.3 with a cold air intake, hookers super comp headers, off road Y pipe, 160 tstat, vette servo, Wheatley tune. I am puttin on a TBSS intake, NW 90mm throttle body 30 pound injectors, 255 racetronics fuel pump, LS6 cam and springs, and if I can find the money [I] will also get a set of Yella terra roller rockers. so what do ya'll think!

moved from the Internal modification section



the stat, trans upgrades injectors, rockers, fuel pump only support the mods that make a difference.

I'd expect a good 35-50rwhp gain. Should put you in the 330-340rwhp neighborhood.

Don't get the fuel pump, or rockers. Wasted money unless you have big horsepower plans in the future, and the stock rockers are plenty good enough.

Also, don't forget to have a retune ready before you swap injectors. A retune is REQUIRED.
