re revs, pst2
to jsmith - PST2 will show over-revs, is very simple to check, and should be done. I'm no authority, but as I understand it, over-revs in range 1 are of no real concern, just means rev limiter kicked in to protect engine on a late upshift. Range 2, however, is a significant red flag, usually means a missed downshift with mechanically forced over-rev and strong possibility of damage. PST2 will also allow you to tell when this happened, and if it was only short episode (ask mechanic number of ignitions in range) that happened 50 hours of operation ago, with a normal checkout now, you MIGHT choose to overlook it.
