FAQ
Is tuning required to run the R1 100HP injector?Custom calibration is strongly recommended to take full advantage of the added flow and to keep smoke/EGTs in check.
Do I have to replace the injector feed tubes?It’s best practice. Reusing old tubes often causes sealing/warranty headaches. Use fresh tubes sized for 2003–2018 Cummins: CPP Feed Tubes.
Is this CARB legal for use on public roads in California?No. This performance injector is not CARB-exempt. It’s intended for off-road/race/competition use where permitted.
What else should I replace during the install?At minimum: new seal kit per injector, fresh fuel filter, and verify lift-pump pressure. For higher power, consider a high-flow or dual CP3.
What’s included out of the box?One reman R1 injector with a new copper washer and O-rings ready to install.
