    HPFP question

    Guest-only advertisement. Register or Log In now!
    When I bought my car previous owner said it had a HPFP. Is there a way to confirm this? I starting to get rdy for a turbo upgrade and I'm reading that the fuel pump has to be upgraded as well.

    You mean a upgraded fuel pump? Some of them you can tell by the piston and others have their name / part number on them? have you tried pulling it off and look?

    Related question. If I don't have the upgraded HPFP, then if I get one and have it tuned with my other mods, will there be any performance increase?

    Most certainly. However, you'll notice it much more with a stage 2-2+ tune that's mapped to utilize it.You'll notice less high end fuel cuts and keep pulling

    Imo you wont feel a drastic difference. But slight difference. If you plan of doing a KO4 and up upgrade your going to need a upgraded HPFP anywayed

    Currently I have intake, exhaust and HFC. If I get the HPFP will that be the right time to get a stage 2 custom tune?
