    All stock engine or what?

    Have any data logs to show that it's rich or a wideband oxygen installed to tell you it's really rich?

    What is your fuel system like and are you running cats?
    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.
