| My Z had similar numbers [cold] to those for years. It was like that immediately after a fresh build. All the while running 600+rwhp and had no problems for a long time... So I wouldn't be worried about it all since they are all pretty consistent. Someone suggested to me to get a new tester. So for the helluvit I did just that. Bought an identical tester, only years newer. Same store had the same shit years later. LOL. Bought it. Did a new test on each hole using each gauge in succession - gauge 1 (old) reads 110. Gauge 2 (new) reads 115. And it was like that all the way through. So the new gauge read 5psi higher consistently. Just saying that the gauge may not be quite perfect either. If you had one hole that was sitting down at 85 or something, then you could be worried.
