That's basically what I do, too (slightly different with the 3B).  But lots of others don't know this and it seems to come up regularly.  I think it's one of the crucial diagnostic procedures for this car and I'd like to see a "public" detailed procedure.

  Brandon, what i do is unhook the ECU vacuum hose, put a short hose on the manifold fitting and plug it. Then, I remove the PCV hose from the igloo and plug that with a lug bolt. Then i remove the airbox to turbo hose from the igloo, and take the igloo off.  I take the cap from a spray paint can and poke a hole in the center of it and put a fitting in from the mightyvac kit. You mau have to seal it somehow, I've ussed blue silicon to do it. I place the paint can cap into the intake to turbo hose and clamp it. After that I use my air compressor at like 15 lbs or so. For me, it worked very well to find all my leaks. Doing that plus fixing my air mixture screw has finally got all the idle/mixture issues solved!
