Tuning the Injector's POP-pressure

I've managed to acquire an injector POP-pressure tester and plan on ensuring all of mine fire at the same pressure as a minimum. As far as devieating from the stock pressure ...

- I realize a lower pressure would move more fuel and potentially make more WOT power (albeit dirtier), and a higher pressure would clean up some idle haze and potentially make a little more cleaner part-throttle power but, over all would move less fuel.

Do any of you folks have experience as to weather there might in fact be a "Sweet spot" as to an idea comprise? How much of a deviation from the stock/OEM pressures?

Or is it simply a matter of dink'in with it a while?

(I'm running an old-school 12mm VE rotary IP feeding some 6x0.016" EDMs where the stock/OEM pop-presure is 245BAR).

Discuss .. . .
