FAQs
Do I need a CP3 conversion or upgraded pump with 50% over injectors?For most 50% builds, yes. The additional fuel demand typically exceeds the safe, reliable capability of the factory CP4. We recommend a quality CP3 conversion or high-output CP3 to maintain rail pressure and protect injectors.
Will these run on a stock turbo?They will operate, but without added airflow and proper tuning you won’t realize the benefits. Many customers pair 50% injectors with an upgraded turbo and lift pump for balanced air/fuel.
Are these brand-new or reman?They are brand-new Bosch bodies that S&S modifies and flow-matches as a set.
Do I need custom tuning?Most 50% builds require calibration changes for best drivability, emissions compliance (where applicable), and to control smoke. Consult your tuner for your exact setup.
What lift pump flow rate should I choose?For 50% over injectors, select a FASS or AirDog system sized for your targeted horsepower and use. We can help you choose the correct unit.
