If you read vacuum at cruse or idle you are hooked up between the throttle plate and the intake valves. Your gage is seeing what your motor sees.

If you hook it up after the compressor and before the throttle plate and there is not a relief valve of some type to vent the excess pressure, you would see boost at idle and cruse.
