do i need to modify these at all??? will the car idle fine or do i need to take out some at lower KPA or anything like that?
That's very close to where I had you. You either enter 58psi for both injector rating & running fuel pressure and use the 48.83lbs/hr number....OR you plug in 43.5psi for injector rating, 58 psi for the running fuel pressure, and use the 42.29lbs/hr number. Both will give you similar results. It doesn't have to be perfect. The fine tuning is done in the VE and MAF tables.

If your fuel line pressuer is different than 58psi (stock), then I would assume that you use that for your fuel rail pressure in the spread sheet.
Reason I ask is because my fuel psi jumps from 60-66 psi. I have a 255 walbro installed. I also have a fuel pressure gauage inside the car.

DD....I believe that's what some people have done (when running the Walbro).
