    You listed nothing about what you did to the engine or anything related to parts. And no tune file.

    So it's really tough to tell you what you have right and what is wrong as far as settings go.

    Only based on the log, it's lean per the fuel trims. The positive trims means it's adding fuel to make it happy.

    The data log is missing many important channels. Things like knock retard, commanded Lambda or AFR, cylinder airmass, injector pulse width avg for both banks. You need to remover the 1 bar MAP sensor channel and replace it with a 2 bar or 3 bar channel so you can see KPA above 104, aka boost. A wideband o2 sensor needs to be installed so you can monitor real time AFR/Lambda, ideally that needs to be put into the logs as well.
    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.
