Ok got edge tuner set on 5 w/fass fuel set up my ? is what is proper fuel pressure at idle ? currently running 20-21 at idle ? is that to high at idle ? thx for your time
I would say its a touch higher than what I see, I run high 18PSI at idle. I say high 18 because on occasion it jumps to 19. At 20-21 you are fine. I would be more worried with how much it drops at WOT.
