you can change how much of the total ratio is used from DI vs port. so that varies but both need supply. if you have larger injectors you will empty the rail faster without flow from the intank supply. i can lower port duty cycle by using more of the DI system but the DI system will require more supply so it doesnt drop pressure in the system. hope that makes more sense to you guys. this isnt a std fuel system so normal theory isnt solid here. i have learned from my experience tuning these kits as well as other with different size injectors and pumps.
