my gauge is always around 30-35psi and when i step on the gas it goes up 39lbs. If that is an accurate reading, it could be a bad problem!! i see you have 530rwhp do you have stock injectors,boost a pump? most gauges (fuel) have a transduser on them, and they aither work or dont work, no bogus readings.

No BAP now 60 inj CPRfuel rail and fuel line is change and CPR fuel presure regulator on it thats work good.When i push the pedal thats going up easily.My problem come sometime when i start the car i saw in my gauge 20 or 30 psi.I stop the car and turn the key on and check the gauge to be sure its at 35 psi if is i start the car and its ok.

if its stuck at 20psi all the time, the gauge is dead

autometer now has a metric version of the fuel pressure gauge that reads in bar instead of psi.
