s you state,
atomization could suffer.

But many injectors do have a max pressure, above which
they *will not* open at all.

The extra cost of multiple injectors (and control
electronics) is not the big deal to specialist and
hobbyist folks like us, it's the performance that we
want. 
So I believe that multiple injectors, either staged,
or of different flow rates, are a more straightforward
method than fuel pressure control via ECU.

Do I hear 'BOTH' ??? (staged + variable rail pressure) :-)

Greg (dynamic range is a wonderful thing, as are mechanically driven high
pressure fuel pumps, since the pump's volume output at least varies with
engine speed !!)
