Does anyone know the actual max flow for the stock fuel pumps on the 3V GTs? People have said it is 4 lb/min, and my stock tune shows 3.99 but the Edelbrock Eforce changes it to 5 and this is the 1580 kit not the stage 2. The Shelby GT which is supposed to use the same stock pump, has a stock calibration that sets the fuel pump at something like 6 or m 8 lb/min.

So which is it?
