Any ideas what could be causing poor performance on a rebuilt engine?
If you know you are right, you need to demand that it be corrected. Compression values? There's always a reason and with modern maintenance requirements the aircraft performance not should be that far off, that's the whole point of engine rebuilds and maintenance. If you are still concerned something is up with it and nothing gets done, call FAA airworthiness. Otherwise, it could kill someone. I've been through similar situations, where an engine would constantly overheat that never gave an ounce of trouble in the years past. Something changed rather drastically and it would constantly go to redline. Forget what the issue was, but there was an actual issue, despite the initial "there's nothing wrong with it".
