FAQ
Do I need custom tuning with 350% over injectors?
Yes. These are high-flow competition injectors and require appropriate tuning, fuel supply, and airflow upgrades.
Are these true SAC-nozzle injectors?
Yes. This set uses SAC-style nozzles that are flow-matched and calibrated as a complete set.
Is a core return required?
Yes, a standard LBZ injector core return is required. See our order confirmation for core instructions.
Will these work on a stock turbo and pump?
Not recommended. 350% over injectors greatly exceed stock airflow and fuel system capacity. Plan for upgraded turbo, pump, lift pump, and supporting parts.
