Violent Cutoff (I mean really violent)

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.
