Used to be that after cooling down I could see 4 or 5 lbs pressure for many days and I don't think increasing pressure after start up was tied to rpm. Now pressure drops instantly on shutdown and is closely tied to rpm to max of 15lbs as the engine is reved up. This looks bad to me although temps in flight are fine. What do you think?
