FAQ
How much power can 22 LPM support?As a general guide, 15% over (22 LPM) pairs well with mild to moderate tuning and a healthy turbo. For heavy towing or sustained high EGT, consider more airflow and monitoring.
Do I need a lift pump with these injectors?It's strongly recommended. A lift pump improves filtration and maintains supply pressure to the CP3, which helps injector longevity.
What's included for installation?Each injector ships with a new copper washer and O-rings. Always verify torque and leak-off specs during install.
Is tuning required?Not strictly, but custom calibration will maximize drivability and keep EGT in check. Monitor rail pressure, pulse width, and EGT.
