    Fuel injectors do not look you have them set up right, the flow rate table still shows around 50ish lb injectors. You need to put in the right flow rate for 80lb/hr injectors.

    MAF fail high needs to be set to 0hz still. Remove your MAF channels from the scanner 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.

    my injectors are more like 94.3 lb injectors.
    no maf.
    2bar.
    10 lb springs in wg's
    appears to be 0 boost or exhaust leak.
    tr6060 manual trans.

    my friend seems to think i dont have nearly enough timing. ill post my latest tune in a moment and log from cold. after its warm then it starts and drives. random idle dips and then wont drop revs below 2000/1900. ill gladly pay for a remote tune.

    What was the issue ?
    High idle and high rolling idle is to do with the idle airflow tables, throttle cracker/follower etc
