Have you done a CKP relearn? Supposedly that helps the ECM to detect misfires accurately.

I have not and I want to but you need a Tech2 to do it right?

Yes. It makes a world of difference sometimes.

When I was doing all my reading about tuning for the transmission and a stall. I can't remember exactly what I did though. I may have only had it report misfires in gear or above so much RPM. IIRC I just googled "tuning for stall" or something like that.
Like everything, there's a million different ways people do things in tuning. I could have read some BS thats wrong. So far, mine doesn't have CEL and it seems to drive/lock up fine....
EDIT: Open YOUR tune and look at your misfire tables under engine diagnostics>misfires>and look at the tables....
Compare those to the stock avalanche tune I sent you WAY back when. You'll see what I'm talking about.
I didn't want to post your tune....

I read somewhere that HPT can do it. I’m not 100% though.

I think you can do that with HPT...

I didn't watch the video. I assumed the process would be the same for any vehicle. Googled it. Top link. Done. My bad

Coincidentally, I was just discussing this a few minutes ago with a buddy that swapped a G8 GT drivetrain (L76/6L80) into an ex-Frito Lay delivery truck (food/kitchen truck for his business). He has EFI Live and says he can do a CASE relearn with it.

You can supposedly do the same in hpt in the scanner functions. Hopefully big d will get his sorted out without having to do it
