Please Ok my Fuel Setup!

Please Ok my Fuel Setup!
Ive been boosted for a year now running on LOW boost. My new h23 is coming back in a week or so and i realized that my fuel setup might not be up to par.
Im running RX-7 460cc injectors on my h22. Ive been boosting about 3-4 psi, and my tuner said, a year ago: "You should be good up to 11psi". He's a very good tuner, and known around the Bay to be one of the best.
My question is this: will the FPR below give me enough fuel for 10-12 psi (coupled with the 460's of course)? I've always worked with just straight injectors, and am new to the FPR route. Thanks, hope ive given enough info and everything, peace.

its not the fpr that supplies fuel... its the fuel pump.
is your fuel pump stock?
the fpr just allows you to control the pressure your motor sees at the fuel rail.

You can't judge injectors on pounds of boost eithe, you have to judge it on wheel horsepower. They are only able to flow so much but in my (limited) experience, 440-460 cc injectors can safely support around 300-325 whp at abou 80% duty cycle which is the limit I want to go.

If you are going to use 440-460cc injectors. Just to let you know. You'll want to use a good source for engine management. AFC is only really good up to 50% duty cycle.
My bro's DSM pushes around 300whp with his 19C set up at 10psi on 93 octane gas.
It's a pretty small turbo, so we went with 550cc injectors. They are almost maxed out with the AFC.
This is also with 255lph fuel pump and stock FPR.
Just to give you an idea of what other people are using for set ups.
