High boost shudder !

Guys,
I have a 1994 Aero, 162,000(running strong!)and have been trying to remedy a high boost/load shudder(fuel cutoff? Clutch?) for a while now. I replaced the fuel pump at 112K, DI cassette at 120k, and BPC valve at 160k.
I experience no problems with the 5pd until heavy boost (i.e. high gear acceleration). I did not notice any difference after cassette replacement but did notice the issue to be a bit more consistant after the BPC replacement. The boost gauge goes in the deep red. This feels great for a little bit but then jerks the car hard until I react and let off the throttle. Would be auwsome if this internet site actually help me fix a problem with an Aero desparate to feel some g's without intteruption. ;-)
