Commanded AFR is stuck at 12.84, are you stuck in PE mode?
Is the scanner correct?
Didn't look at 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 forgot my laptop moved and bounced the connector, I posted the other one that says 73 degrees
The 95 degree log has an issue, the commanded AFR is stuck at 12.84 while the 73 degree log is normal with the commanded AFR back at stoich.
That is likely why you see such a huge difference. I wouldn't trust that first log at all, something is clearly off with the numbers as it shouldn't ever be stuck at 12.84 commanded air fuel ratio under normal operating conditions.

That was my fault, my cord whacked my work lunchbag and came loose so plugging it back in skewed those numbers a little.
