We have a 45 and a 47E and run the same temps as you do. As I understand it running hotter means more blade erosion and a more expensive hot section inspection. We had BE99 engines at a past operator I flew for and those things sometimes would barely make required tq at max N1 and would temp out early. I was told it had to do with worn turbine blades and pilots abusing the hell out of them.
