I typed in your 460hp N/A car with 42lb injectors on the websites fuel analyzer and this is what is came back with. I understand this is based on a stock compression 302, but it's still going to be the general idea. Hope this helps.

Total fuel consumption under wide open throttle: 230 lbs/hr
Minimum fuel pump volume required: 138 L/hr
Optimum fuel pump volume required: 165 L/hr
Injector size needed at stock pressure (40 psi): 33 lb/hr
Pressure required on current injectors to simulate needed size: 24 PSI
Your current injector status is: OVER INJECTED

Yeah I thought the same thing.

BUT......

My tuner told me to buy these parts so I did. He assures me that tuning it will be easy money and I will have room to grow.

I overkilled everything on the new build and only bought the best parts.

After this I hope to actually spend money on stuff like rims and paint.
