anyone running Greddy profec-b boost control?

I just picked one up on the cheap and wonder if anyone else is using this.  It's a dual setting controller; will I want to have a High and Low setting, or just run it high?  I'm not sure what kind of boost to expect.  I've got a T3 on a GTD with 3" exhaust and stock intake mani.

Here's a more direct question: Can I run this boost controller and a boost gauge off the same vacuum line from the intake manifold, or will it diminish the readings for both?  Not sure if splitting the volume will affect boost readings.
