    are you sure you performed the test right? anything below like 100 and the motor probably wouldn't run.

    Given the location; I'm assuming the unit of measure is bar. If so, that's about right and you're just fine.
    12bar=~174psi
    13bar=~189psi

    Sounds right; about a 9% difference which is well within spec of what's suggested(which is about 15-20psi difference, or about 1bar)..

    How accurate is the tool you're using though? As I'd honestly doubt you could be on 12 or 13 spot on.
