To Ed, Bill, and others,

Remember that increasing your fuel pressure increases the volume through
your fuel injector. Corky Bell wrote, "Fuel flow changes through a nozzle
are proportional to the square root of the pressure change across the
nozzle." (p92)

Some guys use a rising rate fuel pressure regulator to enrichen the mixture
of turbocharged systems. The regulator has a diaphram hooked to manifold
pressure and it increases the fuel pressure and therefore output as boost
increases.
