    I don't understand what you are asking.
    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.

    The idle speed and min airflow table are pretty close to what I typically end up with for that cam. The overspeed spark table is a little goofy looking. It should be more linear and I'd back off of the peak number a bit.

    It's pretty common to see those throttle body's need a good cleaning. Make sure there isn't a bunch of carbon on it.

    I had an 06 model that I tuned 3 years ago. It ran great for 2 years. Then it begin to go dead just randomly. I replaced the throttle body and it was perfect again.
