Thread: Fuel Pressure

  1. #1

    Default Fuel Pressure

    Just curious about something. On the handheld and in the Sniper software you can enter the Actual System Fuel Pressure in the appropriate section. Does this have any effect whatsoever on the system performance? In my case, as I use the Corvette filter/regulator, the fuel pressure is 58 PSI. I entered the fuel pressure into the EFI software and uploaded the tune to the ECU, but the handheld still displayed 60 PSI, so I changed that to 58 PSI as well.

    Thanks Danny. I don't recall seeing that in the Sniper instructions or the Sniper Tuning Manual.
