I evaluated PI and the GMP program extensively before making my decision. Knowing PI is backed by a Honeywell was the deciding factor. If you are considering overhauling your TPE331, the PI GMP is the way to go. It was for me. I now have 7000 hour engines that are forever young under Honeywell backed program -- who can beat that?
