    I assume you wrote the tune to the vehicle with the VATS turned off right?

    Are you still using the MAF sensor from the donor?

    What about other sensors and various parts?

    Have a log file?
    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.
