planning on dynoing this weekend and im just trying to get an idea of what i should be getting. my original goal for this truck was 500 hp. now im shooting for about 450... with my current set-up am i going to hit that? if not what else am i going to need? my sig will give you a general idea of what im running. i know eventually im going to need a turbo, im running out of air at high rpms. appreciate the input fellas.:thankyou2:
