I will know tomorrow if the dme resolder of the injector controller area did the trick. I tried the dip stick drip test as described previously and Tue results seemed reasonable. I still have not seen how much fuel pressure one should have after an hour or two.
*edit*
Rats. Still problematic. =( lumpy/car shake still. Now the question is, is it temperature driven, or just after sitting 'overnight'. Oy.

Sure,
It was dropping within spec, no leaks. Clarks garage has the spec. The Fuel Pressure gauge (ProSport) works great.
Running rich because I have a cam, and vacuum is 'different' than spec because of that, and the 3.0FPR is over-kill, even with the A-Tune, so back to 2.5 and it's much better. Could probably use an adjustable.
