I can do this test with the same gauge I'd use to measure boost right? If eventually I'd like to have that info available from the cockpit, I could just buy a "boost gauge" and an A-pillar mount and measure vacuum that way ... two birds with one stone right?
The alternative being to hit up the local FLAPS and buy a cheapie vacuum gauge ... Is there a port somewhere on the intake manifold to connect to? Any gotchyas or special procedures to follow?
