higher pressure almost always atomizes better. the only exceptions are when the pressure goes so high that the solenoid holding the fluid back has trouble opening..

i remember when our FSAE team did some research on the effects with normal fuel injectors, running them around 75psi instead of the rated 43, and gained a couple % across the board on the engine dyno (not chassis dyno). on a regular car it would be negligible, but it was worth it on the ~500lb formula car..
