Hey guys, i have some issues with occasional very small misfire mostly on 4,5,6 gears from bottom ( approx 2000rpm ). Mostly it happens on WOT in 6 gear. I saw there is timing correction -6 on one valve. I recently changed sparkplugs, 1 step colder NGK and gapped them to 0.22inch. What do you think about my graph? Should i put OEM Bosch spark plugs with no gap? I dont have any codes or even shadow codes.
Car is 2011 E90 335i - N55, running MHD V1.60 STAGE2+, Wagner cooler + Wagner sport catted downpipe & Burgermotorsport intake.
5th to 6th GEAR WOT /
