I bought my 31002 kit in October of this year for my 67 GTO and I am having fun learning the system.  One of the questions that I do have is the boost / vacuum reading on my Fitech unit.  The car has 12" vacuum with a gauge but I get different reading on the hand held all the time ( 6.5, 4.3, 1.2) but never close to the 12" actual reading.  Should the hand held be reading 12" or close to it?

Thanks!
