Here's a big 'saalute!' to Murray He called just now asking about--among other things-- an engine calibration file. Seems there are many variations of the C-7 and his able to produce 330 HP.

I've since created an Engine File and added it to the collection: Engine Calibration Files From that link you may download the entire set or just pick yours out and save it to your c:\VMSpc directory.
