    that sounds about right for vacuum pressure but the boost pressure is what u need to obtain to see if its working ok , on standard boost control set up then it should be about 0.7 to 0.9 bar sometimes 1 bar mines runs at 0.8 and vacuum pressure anywhere between -0.8 to-0.1 depending on how much u push the throttle , push the throttle to the floor in second gear when u get to about 2300 rpm and it should go from negative vacuum to about 0.8 at about 5000rpm it will get there quicker than 5000rpm but it should hold peak pressure at about that rev range if it doesnt then the gauge may not be reading right or u have a boost problem or leak , just to ask also where do u have the boost gauge plumbed in to ?

    I just drove to wendys for some food and took mental notes of myreadings. Peak is reading .04 MPa....if i slam the pedal, i get .05 or .06. idle is at -.09...-.06 sometimes.

    The gauge is connected to the BPV via "T" vacuum connector. The vac line to the gauge is actually smaller, but all lines are snug tight. I'll keep you posted if anything happens.
