That sounds a bit excessive to me. Might be time for a new modulator - they're not that expensive. This is a medium PITA job, as it's hard to see well enough to get the new modulator in place with the O-ring properly seated (so you don't have an ATF leak when you're done).
The modulator should hold a steady 15" vacuum until you release it by flipping the valve on the Mity-Vac.

The OES replacement modulator units look like they are only $35, so I'll order one today. Dave, I looked on your site for some modulator R&R but couldn't find it under the tranmission section, would it be somewhere else? It is tight in the tunnel, but until I know what I need to get it out I'm not sure how nasty it will be.
I'm assuming I'll have to drop the pan and do something on the back side as well?
As far as playing with removing the Vac Amp, I'll wait to "experiment" until after I get the car working on the stock config, and then look at "tweaking"
