Boost guage is meant to measure the pressure as it enters the manifold (or that's what it says in the manual anyways) so best place is a tee of an inlet manifold pipe, or (if you have one) the little barb coming off the throttle body.

Saying that, you may wish to tee off just next to the MAP sensor to be sure that what the ECU sees corresponds with your boost guage: not that there will be much difference.
