Another lean of peak question
The logical time to put in an engine analyzer will be during annual when the other things are being done. I just came out of annual, so it will be a while, unless I decide to ground the airplane for a few weeks at least.
For 25+ years I've run my turbo 337 ROP at 75% around 100F ROP. All has been fine.to get
I have a dual engine SHADIN (feeds the avidyne IFD).
I find the leaner engine and richen it to 100F.
Then make the richer one match that, the same fuel flows and keep my fuel math simple.

TCM in video and documents say that you cant hurt your engine at 65% or less no matter how much you lean.
I already have GAMI in front and rear (last annual).
So for an upcoming trip I could
OPTION A. Continue fast at 75% 100F ROP,
as I have for years, or
OPTION B. Slow a bit, at 65% or less and LOP until engines (w GAMI's) start to wobble,
then richen a hair. Remember, according to all sources, no detonation below 65%.
Keeping an eye on my single CHT for each engine.
What are the risks, if any?
What say you all?
