hey everybody....just went to get dyno tuned with my procharged trans am...i found out my injectors are not big enough to support my setup...so now i have to upgrade my fuel system....my question is will 42#/48# injectors be enough??? do they have to be low impeadence or high impeadence whats the dif.?.also will a 255gphr walbro fuel pump be sufficient to support my set up??? Im lookin at about 500 to 575 crank hp...thanks for the help

Id go with 60#s atleast, 1 walbro 255 would be getting close to limited out with your goal too.

Walbro with 60lb or 80lb high impedance injectors should get you there. If you are already buying injectors I would honestly just get some of the new 80lb high impedance injectors. Not much price difference between the two. Those will take you pretty damn high if you start getting boost happy. Low impedance you need an injector driver box to convert the signal for your stock ECU.

How much a 255lph pump can do depends on if it's return style or returnless. Return style you can get up over 500rwhp with a single 255.
