OK I logged 2 runs (attached) both over the same route, holding everything as consistent as possible. The one named "cold-run" was done with the engine cold, and is when I have the trouble. "warm-run" is with the engine warm (running in closed loop) and everything is OK.

I was like whoa when did I start this thread? 
I wish I could help you GMC DUDE but I can't remember what exact was changed but I don't have this problem anymore. It was something in the tuning though and I've changed engines again since this thread was made and I'm running a whole new tune.

Well I changed the idle airflow for in-gear to the following:
17.22 15.23 13.77 12.55 11.53 10.5 9.43 8.38 7.2 6.21 5.3 5.3 5.3 5 5.25 5.3
I saw one lean spike but that was it. Driveability seemed better but then again it didn't get very cold last night. This would probably be a better winter project.
