FAQ
Does this include both the 14mm High-Speed CP3 and the SP3000 supply pump?Yes—this model is the CP3-DMX-14-HS-SP, which pairs the new LBZ-based 14mm High-Speed CP3 with the SP3000 mechanical supply pump for a complete high-flow feed and high-pressure solution.
Do LB7/LLY trucks need tuning?Yes. 2001–2005 LB7/LLY platforms typically require custom tuning to take advantage of the increased pump capacity and maintain proper rail control.
How much power can a 14mm High-Speed CP3 support?It’s designed for very high fueling demand. Actual horsepower depends on injectors, turbo(s), fuel quality, and calibration. Pair with appropriate injectors and lift/supply components for goals above stock.
Is the pump new or reman?New, LBZ-based CP3 that S&S modifies to their 14mm high-speed spec.
What else should I add to my cart?At minimum, a quality chassis lift pump/filtration system, fresh filters, and any worn rails/sensors/lines. See the Recommended Parts links above.
