FAQ
Are these genuine S&S Diesel Motorsport injectors?Yes. This is an all-new S&S 30% over SAC-nozzle injector set engineered and calibrated to OE-level standards.
Do 30% over injectors require tuning?
For best drivability, emissions compliance, and power, custom ECM calibration is recommended when stepping up to 30% over on an LBZ, especially with additional hard-part upgrades.
What supporting mods are recommended?
A quality lift pump and a strong CP3 (e.g., S&S 12mm LBZ-based CP3) help maintain rail pressure and maximize the benefit of larger injectors.
