Bryan, If you are still testing today try this... measure the voltage output of the digital controller (12V positive output to the fuel pump) and if it measures 12 volts before you get to peak rpm then you know the fuel pump is not large enough. From my understanding... the digital controller increases the voltage to the fuel pump as the demand for fuel goes up- to maintain the desired fuel pressure. If you measure 12V output at the controller before peak rpm then your out of pump capacity.

Carl helped me to size my fuel pump and I believe that he said when you get around 600HP then you need the CTS-V pump like Ron said. Carl is a great resource for help. Also.. the capacity on the 5th gen pump was 255 liter per hour rather than lb/hr.
