I run it 2 divisions below redline temp ie 700/720 or so. It's stock standard except for avionics. So much so that Simcom used it for a photo model when they were updating their manuals.

Engines are 3600 tbo with a hot section inspection at 1800. At least the PT6 is easy to split to get to the hot section.

Can't give costs because I don't get the bills & sign the cheques.

As I recall, the Garrett in a C441 can run to a 5000hr tbo, with something like a 75gal/hr fuel burn while doing around 300kts.
