Nope haven't had the vacuum checked. The guy there says it has a good vacuum. Honestly I'm clueless to these things though. All I care about is being able to bench with it. I thought they operated at a higher rate than 6psi anyways. I thought it was more along the lines of 14psi. So you are saying that its losing tons because the release valve is popping off at 6psi? The other problem is the damn head freezing solid to where you can turn the hand valve to withdrawl the ln2 :(
