DTC P2101 and KR
I have had a check engine light since the wait4me tune (did the relearn). I took it to a local parts store and they diagnosed something along the lines of bank 1 and 2 out of range/performance Now I check it out with my scan gauge and it says P2101. I have looked and searched everywhere and can't find info on that DTC. My truck was getting ~1* KR when I cleared the code and when my SES light comes back on it gets ~5*KR. Is the SES light making it get KR? How much does 5* hurt it?
Any info is appreciated

Can you get me a link to where you found the GM code for it? I am finding it weird that I could not find info on it before

well if i came on at the same time you got the new pcm i would say it would be the tuning... pcm could have possibly got damaged during shipping.... i would shoot them an email with that link in it and see what they say... also double check all your connections to the tb
