You need to log all the channels that relate to spark timing.
Anything that can pull timing is what you need to be logging. So any of the spark correction tables like the IAT, ECT, torque mngt.
I can already tell you strictly based on the last log you are losing 13 degrees of timing from the IAT temps. The temps are around 125-135 degrees and that IAT spark table is pulling 10-13 degrees.
I've never seen a command idle speed of 361rpm before either. I'd try asking for 600rpm all the time when it's warmed up too.
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.
thanks for lighting I'm working on it
