    Spark issue at launch on drag strip

    Hi all, i've been looking through older logs and looking at my slight slow 0-60ft times compared too my old rover/buick engine set up and noticed a large dip in the spark as i launch at 2000 rpm. i was wondering if you have any suggestion before i take it on it's next trip, thanks John

    Turn off burst knock, that can yank a bunch of timing when you stab the throttle.

    Set the enable delta cyl air table to 7.900.

    Turn off brake torque mngt in the system options too.
    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.
