FAQ

• Are these true 150% over injectors?
  Yes — this set is specified at 150% over stock with SAC nozzles and S&S calibration.
• Do I need a lift pump with 150% over injectors?
  Highly recommended. A quality lift pump helps maintain supply pressure and protects the injection system under heavy load.
• Will my factory CP3 support these?
  At this size, plan on an upgraded CP3 (or dual-fueler) and proper air to fully utilize the injectors.
• Are these street legal?
  Legality depends on your local emissions rules and usage. Many high-flow injector sets are for competition/off-road use only.
• Is a core return required?
  Yes. Reman sets generally require a core return; check the core terms before purchase.
