What is standard fuel pressure on the Titan's 5.6L??? Also, what have those of you with an OBDII interface been seeing fuel pressure wise???

With an Auto Meter Pro mechanical gauge mine idles with 55psig. Under full throttle on or off the nitrous I am running 51 psig. You results may vary. If you're trying to jet nitrous, assume it is less pressure than that until you know for sure to prevent anything bad from happening.

Is that 51psi on or off the bottle??? Thank you! Woops you answered that question above, nevermind.

Here's what the service manual says about fuel pressure at idle.

At idling: Approximately 350 kPa (3.57 kg/cm2 , 51 psi)
