Is
it 73% power no matter how I set the MP, so long as temperatures remain in
control? If that's true, why would I select one MP over another
(realizing I can't run wide open throttle)?
Yes,
it remains at 73% power. When flying LOP, fuel rate is power. You
are much “leaner” at 32 inHg than you are at 30 inHg. Add
fuel at 32 inHg and you will go faster and your cylinder heads will still stay
under 380 degF. Nobody likes a slow airplane.

My
ES-P has a TSIO-550E with GAMI injectors, and I’ve recently been through
advanced pilot's web LOP
course. But I'm still unclear on at least one point.
My TSIO-550E will happily run at 17.5 GPH at a MP of any of 30, 31, 32 (among
others). All cylinders remain below 380, and TIT is reasonable.
My understanding is multiplying 14.7 x GPH yields HP, in this case 73.5% power
