There really is no simple change this or change that to get your answer.
See how it's running and go from there really. You may have to re-tune the VE and MAF table completely and work on everything that needs it.
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.
