Its on the passenger side right? There was a guy in my club that wanted his boost to be read on his Whipple and a guy stood with a gauge on the pass side of the car right next to the blower while the car was on the dyno going WOT.

There are other places you can tap a vacuum line. I chose the line on the drivers side.
