FAQ
How much power can 200% over LMM injectors support?They’re intended for high-output competition builds. Actual power depends on air system (turbo/s), CP3 capacity, fuel quality, and tuning.
Are these injectors flow-matched?Yes. S&S flow-matches sets to tight tolerances for consistent cylinder-to-cylinder delivery.
Do I need a lift pump or upgraded CP3?Yes—200% over injectors typically require a stout lift pump and an upgraded or stroker CP3 to maintain commanded rail pressure under load. See recommended parts above.
Is a core charge required?Yes. A core return is required for reman sets.
Will these fit my 2011+ LML?No. This set is specifically for the 2007.5–2010 LMM platform.
