my name is travis, new to this forum, i had a 2000 sierra with a 5.3, full exhaust, cammed, built 4l60. i recently traded it in on an 08 4.8, 4wd "pooch" i'm trying not to void my warranty until it's out. 3"lift, badly done, extreme cv angles my upper control arms ride on the steel bump stops off the frame. blocked the rear, maxed out the stock shocks. flowmaster cat back with a single 2.5 pipe. k&n drop in filter descreened the maf, polised the maf body. drive by wire, bad throttle responce, "why did i buy this?" it's on 33's with horrable incubis offroad wheels that are 10 months old chrome that looks 20 years old. pits... give me some info on picking up power. wanna keep the warranty, so no spraying, or turbo kits, maybe a magna charger, i could put it back to stock in a day, if i do need warranty work. i'm interested in rockers, full exhaust , nothing that's noticeable. like a cam lope, or n.x. selonoids, what mods work, what's hype?![]()
