duty cycle

Hi all, Looking to pick up VMP's Fuel Pump Booster setup for my GT500. The car is already modded and dyno tuned and running 18psi on a ported and 2.2" pullied Eaton. My recent data logs are showing that the fuel pumps are basically maxed out and so I figured going this route would work out...

Hello, is there anybody who can say what is the frequency of the duty cycle signal for fuel pump driver module. The engine is 2003 4.6 S/C. I'm going to install Emtron's KV8 ECU here and don't know what kind of PWM should I use. yours sincerely Jukka
