MBenz- How did you disconnect this sensor? Did you unplug the electrical connection or what. I ran the vacuum line from the intake to the injection pump, completely bypassing the sensor, without any luck. I was told that this sensor cuts fuel if boost goes too high as a protection for the engine. I still think without EGR that the computer cuts boost also, as I do not hear the turbo whine.

I think Vhunter has the right idea but I don't know if I am ready to try that yet. MAF is the culprit. I don't know if the MAF has other functions other than EGR tattletale - could mess up other stuff doing the diode thing. I have not checked to see how many wires even go the the MAF.
