    Does anyone know the normal range for the FRP Actual PID (fuel rail pressure) for a 2018+ GT? I have seen it drop to 500psi and up to nearly 3000psi and I had a P008a code randomly once for low pressure detected. Thx for the help

    I’m curious do you have or did you install a DW fuel pump?

    The reason I’m asking is because I had that same code about a week ago but I have a DW fuel pump in mine and my tuner told me to check the hose it may have a crack or popped off. He said he had a F150 that had the same code and it was a hose issue with the DW 400. Literally after the code popped up I filled up with gas so I’m trying to drive most of the gas out so I can pull the fuel pump out and check the hoses. I’ve been watching my FRP as well

    Any updates on this ?
    DW400 with BAP stage 2 whipple and I got the code last week.
    FP (%) PID also went from being flat top and steady @42 to all over the place with spikes .
    I am assuming it’s an issue with the pump .

    Fortunately I am having my return fuel system installed this week but want to make sure it’s not anything else .

    Thanks
