Also, make sure the VCV on the side of the injection pump is set correctly. This is not a "seat of the pants" [...] but basically you loosen the mounting bolts, have a helper press the pedal to the floor (or pull the throttle cable to WOT), gently rotate the VCV (from full CCW turn it CW) until resistance is felt, then tighten down the bolts. Often it ends up right in the middle of the adjustment range.

Dave,
Does this apply at all to the 617 VCV configuration as well, or just the six-cans? I'm replacing my modulator today (it's leaking down in seconds,) and hoping that the spring on the old one is broken, as I have the most erratic shifts one could imagine, with lots of unpredictable flaring and the occasional case of whiplash. I can't seem to adjust the modulator for firm shifts (or at all.)
I have never heard of this and can't find [ed:doesn't mean it's not there] any reference to this in my FSM, but it's one of those PDF ones where the search function doesn't want to work...
