The specs call for 178 psi and the engine should be at operating temperature. I would think that anything above the 150 psi mark and you're probably just fine. Primary thing to look for would be consistency across all cylinders. Variations of 10 or 15 psi is nothing to worry about. Having 1 cylinder significantly different than the others would probably indicate a problem. Check it twice to make sure it wasn't something you did during the check that caused it.
