The proper solution is to buy bigger injectors and use them at the pressure they are intended for  |
I'm not much of a machinist, so all my tinkering would be in the control system, which I likely would not keep simple. 
I see a fair amount of success on other platforms with higher fuel pressures, up to about 90 psi or so. My impression was that as pressures go up, atomization gets better.
Guessing that idle quality at the track as long as it starts and doesn't die isn't too critical?
