There is a lot GOOD to be said for the idea of using a rising rate fuel
pressure regulator to effectively widen the dynamic range of the injectors.
This can GREATLY improve streetability, and fuel economy to some estent,
too.

Even with a quality RR regulator, though, I think one ought to plan to have
a fuel pressure transducer in the rails in order to give feed-back on what
the regulator is doing to the ecu. (Along with software that corrects for
fuel pressure variations!)  Just too much room for problems otherwise.

IIRC, Carl Summers had a source for a _REALLY_ nicely made unit, and
someone here had a picture of one of these units installed on an engine.
NICE looking unit. Most of this type of unit out there on the market do
appear to be junk waiting to happen---
