Maybe it has something to do with how much of a load the engine is under on = the ground vs. in flight. Anyway, I'm on the right track .

Brian;

I noticed the same thing = – slight difference. When tuned on the ground there would be just a missed beat at the stage = point in the air. It would certainly get my attention until I realized = what it was. Tuning in flight made it go away, and staging is seamless. = It makes some sense – there is a different rpm vs Map relationship = when in flight.

Looks like I’ll be back out = doing some re-tuning when the weather clears. I thought I was done with = all that some years ago; but things change.
