In my Dakota when I try to run LOP I have 5 cylinders pretty leaned and about 60-70 LOP and FF is 11.5 @ 70% at 9000 ft but cylinder 6 seems to hit peak EGT 1450 or so at the same time while others are 1390-1420. If I lean any further the vibrations start and going rich puts them all in 1420 range. Still new to this as I have always run rop in my warrior. I leaned this based on one cylinder 2 or 4 or lop from 830. All CHT remain within range of 320-370 in cruise. So looking for guidance.
