Ok so your cruising numbers look good. Idle I would like a lower number but not terrible for ltft but the huge fluctuations in short term don’t look so good (although not a vq expert but that doesn’t seem great to me). How many miles on this engine? No roughness or intermittent misfires at lower RPM/idle?
