FAQ
What kind of power can 100% over late-5.9 injectors support?With adequate air (single or compound turbo) and a stroker/dual CP3, 100% over injectors can support robust street/comp power levels. Actual gains depend on turbo(s), fuel supply, tuning, and drivetrain health.
Are these true SAC nozzles?
Yes. S&S builds late-5.9 injectors with SAC nozzles and flow-matches sets to tight tolerances for consistency.
Do I need new connector/feed tubes?
Yes—always install new tubes and follow cleanliness/torque specs to prevent leakage and balance issues.
Will my truck smoke more?
Uncalibrated, any large injector can smoke. Proper tuning and adequate airflow are critical for clean power.
Is a core return required?
Most late-5.9 injector programs require cores. See the core instructions on this CPP product page at checkout.
