Is the injector data correct?
Something maybe seems off, the flow rate looks like something bigger than 80lb/hr injectors.
I don't see any wideband data in the logs either.
I see other weird things with the idle and base running airflow stuff that isn't right. Desoot mode should be disabled too.
Put it in speed density and tune the VE with the wideband, then tune the MAF with the wideband.
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.
