Anyone have problems with fuel preasure not being steady? I have a GT supercar pump in Mustang GT canister and was working fine. I'm curious if its the pump or the controller taking a crap. Fuel psi bounces from as low as 20 to as high as 50 and most of the time is jumps from 30 to 45 at idle and at a steady throttle position.
