Oh, Kneale! Now what did I do? ;-)
Make sure the hoses are attached properly (I'll see if I can't take a pic
when I get home). Otherwise, this is telling me you might have the
wastegate cranked down too far -- did you adjust the preload on that? In
any case, it appears ECU sees overboost and is cutting power to the fuel
pump -- hence your violent bucking.
