It wasn't so bad. I'm just too big for her. Disadvantage of being graced with a small wife.

That's correct. My car will only boost to around 0psi if the tranny is not engaged.

Pressure ratio. Without the inertial force of the drivetrain, your pressure ratio is too large to build boost. Like trying to inflate a tire, the larger disparity between the original pressure (exhaust manifold) and the secondary pressure (intake manifold), the more difficult it is to make boost. Your manifold has a lot to do with that, along with the size of your turbo and cam profile.
