You're killing me. I need to know what that corresponds to with an Autometer Phantom gauge

nope... closer to 18 or 19 inches of mercury (autometer 18/19 "Pounds" of vacuum)

My car working properly is about 550 mm of mercury, but when it's acting stupid like it's on 3 cylinders or missing is about 450 mm of mercury...

Vaccum gauges don't typically read in PSI. They read in mmHg or inHg.

I was wondering that, but he said he needed psi. Does anybody know what the Autometer guages read vacuum in? mmHg or inHg?

I wouldnt make that assumption. I can open a vac line to air and the vac stays within 1 in of Hg from where I started.

I tried this to see if the gauge was a good indicator of a vac leak....I found out it is not.

Mines 23-24. Can hit 25 on a good day, usually when the humidity is lower, if it matters.
