StarquestRescue Posted April 16, 2010 Report Share Posted April 16, 2010 i'm up to 15psi now. and it pulls really hard to 6500rpms. i love it. i dont think i need any more then 20psi. goin to work on 18psi nextYou will likely run out of injector flow at some point. Still on the stock ones or running two secondaries? The more rpm the less time the injectors have to squirt the fuel in. What rpm are you getting the 15lbs at?
