C,

it is
time to point out that most engine and aircraft manufacturers do not
recommend running engines lean of peak.


Not quite. MOst don't say anything about it. The new ones tend to
provide settings for it.



New what? Manufacturers? Engines? Planes? I don't know of any Cessnas, Pipers
or Beeches that provide settings for it. Or Lycomings or Continentals. What
does Cirrus say?

As you know, LOP has been written about quite a lot in recent years. The one
thing I have noticed is that it is a lot easier to get a high performance
engine to run smoothly LOP than it is for the trainer types.
