    Delete the 1 bar map channel, only log the 2 bar channel.

    Work on the fueling. You are asking for 11.67 but the wideband is showing like low 10's.
    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.
