    VE and MAF aren't dialed in yet, fuel trims show way positive long term trims. Meaning either a large vacuum leak (less likely) or the airflow model hasn't been tuned yet to bring the fuel trims back down towards zero.

    Also o2 sensor information, throttle position and injector pulse width are good things to add to your logs.
    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.
