Default Calculating injector size !

Right you clever guys.
Need to increase size of my injectors and need some feedback from someone who knows.
its a turbo V8 with low impedance injectors.
Dont want them unnecessary big, just enough for the power i am after.
So 400HP say 85% duty cycle, .65 BSFC and the kicker is the fuel pressure is 58 psi
Most injectors are flow rated at 43psi and i have seen that at 58 psi an injector should flow an extra 17%
Anyone know their way around specking an injector ??
