FAQ
Do I need a modified CP3 or dual CP3 with 300% over injectors?Yes. For stable rail pressure and proper atomization at this flow rate, plan on a stroker CP3 or dual CP3 plus a quality lift pump and filtration.
Are these street legal?No. 300% over injectors are intended for race/competition use. Consult local and federal regulations before installing on public-road vehicles.
What tuning is required?Custom tuning calibrated for 300% injectors, turbo configuration, and fuel system hardware is required to manage smoke, EGT, and driveability.
Will these fit all 2003–2004 5.9L trucks?They are designed for the early common-rail 5.9L (2003–2004 Ram 2500/3500). Verify your VIN/emissions label and build date when ordering.
