Boost is "pressure" and not vacuum.
And, yes, there is a pressure line that you can T into. On the driver's side of the manifold you'll find a nipple with a hose attached........at roughly the middle of the manifold. The hose will have a small hose clamp holding it in place. You can T into this line to measure boost.
You'll have to route the gauge into the cabin so that you can read it while driving. Get the engine above 3000 rpm at full load and read the boost gauge.
But, prior to any testing in motion, you should probably check the impeller for radial or axial play. Maybe the shop was knowledgeable and could see the turbo was in poor shape...........maybe not.........??
