Major Boost Problems...

[2GDSM]

2g Spyder, stock except I got a 1g bov, and a http://mid-atlanticfasteners.com/mbc.htm MBC, after install I had a vacuum line from the compressor housing left over, and my boost creeps to 25psi, all the way to fuel cut. Any ideas on how to fix this?

You installed your mbc wrong more than likely.

Pressure source from the compressor cover or bov line to the bottom of the mbc (inline with the adjustment screw) and the line out of the side goes to the wg actuator.
