Do you have a target HP number in mind? Is your ECU tune / wastegate set up for 17lbs steady state or peaks at specific RPMs?

Here's a link to a handy calculator: https://fuelinjectorclinic.com/flow-calculator

Assuming your target is 400 HP, your fuel pressure is 45 PSI and you choose a racing duty cycle of 85%, this site is suggesting a 600cc injector is the one (note that's about 80% larger than stock which I think is 325ccs or so).
