9\'s are from pip told me when mine was done are good and so from that you should be pleased i know i was.

9\'s would be very good on some new engines. Is the engine brand spankers, or has he used a piston compression tester, did he give you a read out to prove?

It is important to take into consideration the RPM that the test was done at.
A proper rotary compression tester will compensate for the rpm anbd do a correction as the readings should be corrected to 250rpm.
