Fuel pressure

[1racer]

What is the fuel pressure spec for the 800 pro-rmk? Is it measured at idle?

anybody know factory spec?

58 to 60 psi. at idle and while operating the vehicle. thats for a 2012

I know this is a little late to put in my 2 cents but what would happen if the fuel pressure was at 62#? I have an issue with a mid range gurgle or misfire that is consistently between 5400 and 5800 rpm. Have been fouling plugs during cold start up too. Replaced injectors, pipe temp sensor, set tps, set pc5 to tps, removed chipped vforce3 reeds and replaced with stock reeds. Wonder if 62# could be flooding motor.

What is the PC5 for? The 2# could be as simple as the gauge you used but is not likely to be causing an issue. I would consider a different map for the pipe? and maybe high flow intake? that you have.

If the gauge is truly 100% accurate (very rare) than extra fuel pressure will cause the entire fuel map to run just a little rich. If 5400-5800 is usually a rich spot on the map then it could be causing your issue. If the gauge is accurate.

Already have high flow air kit. Dropped sled at dealer today. Gonna let my normal dealer check it all out this week.

I see Justin of Silber turbos fame is saying to run 38-42 psi fuel pressure to tune turbo engine.
Is the fuel pressure adjustable ? I don`t think so but I have been wrong once before.
