    Injector flow rate, offset vs volts, short pulse adder, min injector pulse and anything else that the injectors come with.

    This is where the data is key. If the injectors you can get your hands on have known data the stuff you input will be easy.
    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.
