what kind of fuel psi is safe for a 99 7.3L? I am running 55 psi with a chip installed and I'm not sure of the safe psi to take my pressure up to. thanks!
I would leave it right there. No need for more. I've ran as much as 80 but lost 10-15 hp in doing so. I've also found running a higher pressure gave me a rolling idle that go real anoying.
