Ya know I reviewed that log again and found it didn't really reflect 100% the context of the fuel or lean cut I observed. It was weird. Problem is I never found it other ran what I posted last. Not sure if that exerpt was in fact when it happened. Sorry to you (Chris likely lol).
I pulled my still nice plugs yesterday to swap in new ones and clean the olds. They were run pre- and post-op. The operation being the new IC

Reviewed them for detonation briefly and took to a mechanic friend who was a motorcycle black thumb (mad max reference) for almost 40 years. He said they looked PERFECT lol.
Last night after my look over of them, I added another .5 degrees timing at the very highest rpm's at high boost for a total of 2 degrees max. I was pretty confident they were fine but we t to see the friend to back up my findings.
Maybe I'll add another 10° and be done with it
