lea of peak

[KJB]

I own a turbo-twinco since half a year.
Mostly cruising on altitude the engines rich of peak, 65%. To diminsh fuel consumption I thought about running the engines lean of peak.
Has somebody experience to set and determine the EGT and CHT, with or without the help of an engine monitor?
and whats about the engine wear and TBO, makes it sense to spare some bucks with gas in the risk to destroy the engines?

Each engine is different. Don’t do it without an EDM type monitor unless you want to save on fuel but spend on a new engine.
