Hey guys I just bought a brand new 04 sonic blue lightning in september, and need some help on what mods i should do first to it. I know some stuff about cars/trucks, but I don't know where to start. Any ideas?? I'm lookin at a pulley/programmer package that will put me at 450 hp. Thanks!!
Welcome! I would go with a 4# pulley, cold air intake, and programmer (from a reputable tuner). That prolly won't get you up to 450 Hp though. More likely around 420-430 RWHP. That is what I found from my experience.
