dont log MAF pid with speed density tune, it will throw off cyl airmass
what spark plugs to you have and are they gapped?

No that this is the cause but being speed density you still need to have your MAF DTC's on first error in the tune.
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 need to have the dtcs cleared? Or turned off. MAF Is unplugged
They are curretnly set to dtc on second error, change it to first error. You can uncheck the SES box.

Its still sputtering and has zero power once its given alot of throttle. Afr spikes up way past what the sensor reads when its given throttle
