    Some people here are willing to help but we need the tune and logs posted here on the forum.

    Provide a more detailed list of parts used as well.

    Who's 60lb/hr injectors?

    What fuel pump and fuel system, return or returnless. Reference etc etc.

    What MAP sensor is it using as well.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    There is an advanced reply box you can click and in that new screen you can click the paper clip attachment icon to attach them.
