hp where? at the fly or ground
i have 400 at the ground and my truck runs fine
if you are running boost in the 20psi area i would think about changing them
480 rwhp the injectors are maxed out, as well as your stock 90 mm mass air unit, and the stock fuel pump is too. So yes, at 500 hp at the motor you should upgrade alot of things.
Ugh.. I am still debating the cage... I know I can run without it.. But only one pass and then go home... lol... That sucks too.. but its either that or find someone who makes the door bars to swing out... still debating on the cage.. dont really want the hastle with it being my d/d.. but I like the idea of the protection..
