    2024 Silverado 1500 L87 Fuel system

    Hi, has anyone upgraded a fuel system in the 2024 ZR2 1500 Silverado?

    The in tank pump has 3 control wires and is small with limited space for a larger pump.
    I have the HPFP and the injectors sorted, just in tank that is the issue.
    Does HP tuners read and edit the FPCM in these?
    Any ideas welcome.
    Thanks!

    All I'm aware of is the Escalade V in tank bucket/pump is a slight upgrade, I've bought one to try shortly. Had HP Tuners Support look at my FPCM but could never get HP Tuners to read it.
