What brand injectors?
What 2 bar MAP sensor?
Post the tune file.
All 3 log files say it's still running stock 33lb/hr injectors and not 60's.
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.

I'm not familiar with those injectors. You'll need to see if you can get the data for them. You will need the flow rate at 58psi, min injector pulse, short pulse adder and offset vs volts data. Then plug that into the calibration.
Some of the boost enrichment and timing tables needs adjustments so that they work better.
A wideband is also needed so the MAF/VE tables can be tuned for boost.
