    Did the throttle body and pedal assembly come from the same vehicle 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.

    Have you finished the swapping process?....no readings for oil pressure, oil temp, VSS....
    The MAF reading is very unstable during the video and 4000rpm is typically where Dynamic drops out and runs on MAF only. Is the intake setup to provide smooth[ish] airflow for the MAF?.
    Do you have all your wiring and ECM earths (especially engine block) sorted?.
    The tune file might be helpful, too.
