K2e2vin Senior Member Mar 25, 2009 #6 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. Last edited: Mar 25, 2009
