Need help with injector size with friends procharged car

[MustangLife]

This is concerning my friends procharged 01 cobra. He putting a 18 pound pulley on his car tomorrow. Right now he is running 10 pounds of boost and his 42 lb injectors are maxed out. Hes putting 510 rwhp right. With a A/F of 12 to 1. I know he needs a tune. Hows his a/f ratio gonna be with that small pulley on there. Its a completely built 4 valve car, stage 3 heads, sean hyland blower cams, manley i beam rods, etc, etc

What size injectors does he need. Hes already got a 1200hp aeromotive fuel system and hes running a FAST SpeedPro.

Any advice is appreciated.

Thanks
Josh

A friend of mine is getting a motor built that is estimated to put down 650 - 700 horses. I'm not going to get involved with the details of the car, but they plan to put on 55# injectors. I'm sure that would be sufficient on his set up.

42 lb injectors should cover 500 rwhp EASY. Those are usually rated to around 700hp. He needs a tune bad.
