I'm definitely not out of the woods, but driving home today I punched it a couple times to watch my fuel trims, and my LTFT was at 3.9. MUCH better than 6.2 where it was at several weeks ago. So from 70, WOT gave me a 3.9 LTFT and 0.0 KR for a good 5 seconds. Once at around 90+ I started getting 2-3* KR.
I've never seen 0 KR above 70 before. IDK why it seemed to run so well tonight, but I doubt it will last.
