- FUEL FILTERS & FILTRATION UPGRADES – protect precision nozzles
- INJECTOR FEED TUBES & LINES – fresh sealing surfaces while you’re in there
- TUNERS & CALIBRATION – scale fuel and timing for 200% over flow
- TURBOCHARGERS – match air to fuel to control EGTs
Helpful Installation Notes
- Use new feed tubes and torque to spec; verify leak-free sealing
- Prime fuel system, check balance rates and rail pressure
- Custom tuning is required to properly utilize 200% over injectors
FAQ
Do I need tuning for 200% over injectors?Yes. These are high-flow injectors. Proper calibration is required to scale pulse width, timing, and rail pressure. We recommend pairing with our Tuners & Programmers category.
Will my stock CP3 and lift pump support these?
No. Plan on an upgraded CP3 pump and a quality lift pump/fuel system to maintain commanded pressure and volume.
What about warranty?
S&S injectors are supported by a manufacturer warranty; see your invoice and S&S policy for specifics. Keep filtration and tuning within safe limits.
Is a core return required on NEW injectors?
Yes—S&S specifies a core return program on Early 5.9 injectors. Dealer core deposits and timelines vary; check your order confirmation.
What turbo size should I pair with 200% over?
Match air to fuel to keep EGTs in check. Many builds step up to a larger single or compounds; consult our Turbochargers category and contact us with your goals.
