Stock IX, electric Prosport 19/20 at idle, car off needle sets one mark below zero. I hooked up an old autometer mechanical gauge, it sets on zero car off and 17 at idle. Have not compared positive boost readings yet, but Ive used Greddy, Blitz, and Autometer, all mechanical gauges in other cars and all land on zero when car is off. Thought maybe the Prosport wasn't caliberated right, but from what iv;e read hear the 19/20 at idle is normal.

sorry to revive this out of the blue..however there was some confusion (with me at least) with reading the proper vacuum with bar gauges (kpa) instead of psi gauges reading vacuum in inHG
here's a link to a converter I found online
http://www.sensorsone.co.uk/pressure...onversion.html
so roughly 19 inHG (normal vacuum) = to 65 kpa
