As of this afternoon, just saw up to 5.7* KR at WOT around 5,300 RPM.... Target AFR is 12.2 (set by me) in the PE table. I still need to swap plugs to see if that helps but gosh, 5.7* ?!?!?! Fuel trims are zero all the way across. Can plugs get rid of ~5* of KR? Maybe I should target lower AFRs in my PE table??
