Listen up bigtim - Ken's right and you're wrong. It's as simple as that. I've exchanged messages with BAX (the OS rep) in the past and he advised just as Ken says. The engines have less than 3 minutes run time on them as delivered. They have been factory started, very roughly tuned and shut down. The limiters are then put on and the engines cleaned and boxed. They need to be broken in properly.

Even if you refuse to believe the obvious truth due to being simply stuborn you will have to admit that it surely won't hurt to follow the proceedure. It doesn't mean running several tanks through on the ground just one, then just run a bit rich for a few flights.
