But runnnig your engine at 30" at 15,000 feet is MUCH harder on the
engine than running 30" at 5,000 feet. The engine runs hotter and
harder.

65% is 65%, is 65%. All equal, no harder. That is the point of turbo
norm. The engine has not got a clue how high it is. MP is the same at sea
level or 15 thousand.

The only argument is the temp. Keep it cool. it is not that hard, nor is
it rocket science.
