My AFR at idle is reading between 13.7-14.7. That is at both extremes. For the most part at idle it is usually bouncing around 14.0-14.4.

Seems like, from face value without data logging, my tuner made it run a bit rich at idle.
Maybe the richness is the trick to keep it from doing what we describe. You would have to just log it to see what the target afr is set at. I suspect you might just have the same issue I had where one bank is at 14.7 and the other is at ~13.7 or so.
