FAQ
Is tuning required with 500% over injectors?Yes. Calibrations are required to properly command pulse width and rail pressure, and to maintain drivability with this much nozzle flow.
Will these fit all Late 5.9 (2004.5–2007) trucks?Yes—this set targets the common-rail 5.9L Cummins used in 2004.5–2007 Ram 2500/3500 models.
Do I need new connector (feed) tubes?Strongly recommended. New feed/connector tubes help ensure proper sealing and avoid contamination issues with fresh injectors.
What’s the difference between “New” and “Reman” sets?Both are flow-matched and built to S&S spec; this listing is the remanufactured set. New sets are available separately.
