My father and I just installed my boost gauge today to see what my vacuum was at idle. I tried searching to see what the correct vacuum i should be getting i hope im refering to the right term.

My car seems to float between 10 and 20 after a time it will just sit between 10 and 20 and then do the same thing again.

Were do you have it hooked up? Should be directly off the intake manifold.
