FAQ
Is this a full set or a single nozzle?This listing is for one (1) nozzle. Order 8 for a complete engine set.
Do I need custom tuning with 30 LPM nozzles?Yes. Proper ECU calibration is required to manage pulse width, pilot/rail strategy, and smoke control.
What supporting mods are recommended?At minimum: a healthy CP3 pump, a quality lift pump, and a rail PRV matched to your commanded pressure. See the Recommended Parts above.
Do you offer other flow sizes?Yes-R2 (22 LPM), R3 (24 LPM), and R4 (26 LPM) variants are available on our site for 2007.5-2010 LMM.
