One more thing. If I put the mini vac on the line going into the firewall it holds vacuum. If I pull the hose out of the pump under the seat the vacuum goes away. Yet, if the pump runs the vacuum does not appear at the transducer. It's almost like there is a check valve in the system somewhere. My guess there is some sort of safety system here that protects the engine if the wastegate transducer sticks. They have provided an alternate way of killing the vacuum in case of failure. This is where the problem appears to be.
