FAQ
Do I need a lift pump with the Double Dragon 120% CP3?Yes. A high-flow lift pump helps maintain consistent inlet pressure and extends CP3 life. See our FASS and AirDog options linked above.
Will this pump work with stock injectors?It can be physically installed, but performance benefits require larger, matched injectors and proper tuning. Pairing with stock injectors may complicate rail pressure control.
Is tuning required?Strongly recommended. Calibrating commanded rail pressure and fuel quantity ensures drivability, power, and component longevity.
Is this pump 50-state legal?No. It is for competition/off-road use where permitted and is not for sale in California.
