I am currently running 52 psi after the cam install. What should I run it at? Look at the mods below. Before the cam I varied fuel pressure from 47-54 psi and found the best to be 49 psi. This resulted in my best time at the track with a 14.450 @94.5 MPH (before the ZZ-9 and Big Mouth Intake Manifold install).
