- 250% over injectors require a healthy CP3, strong lift pump supply, adequate turbo/airflow, and proper calibration.
FAQ — Do I need new feed tubes when installing these injectors?
Yes. On CR Cummins, old feed tubes can cause sealing issues and injector return leaks. We always recommend new tubes and seals during injector replacement.
FAQ — What turbo and pump do I need for 250% over injectors?
Plan for a high-output CP3, a quality lift pump, and a turbo sized for your power target. Insufficient air or supply pressure will cause smoke, heat, and poor performance.
FAQ — Are these streetable?
They can be used on street-driven builds with the right air system and calibration. Expect more fuel than stock even at light load; good tuning and turbo sizing are essential.
FAQ — Do these carry a warranty?
S&S Diesel Motorsport injectors include a limited warranty when installed and used as intended. Keep fuel clean, maintain lift-pump pressure, and follow proper install procedures.
