DCB,
That's very good! Care to compare code?

TJ,
I'm confused. The regulator is, as you say, a mechanical device designed to keep the pressure drop across the injector nozzles constant with varying manifold pressure so the pulse widths don't have to compensate for this. I have an accurate fuel pressure transducer on the system in my boat, so I can log pressure and compare it with manifold pressure. My logs show the difference as being relatively constant right cross the range of manifold pressures. At no point do any of my pulse widths decrease with load, but that's a function of my fuel maps.
