FAQ
Do I need tuning with 60% over injectors?Yes. Proper ECM calibration is required to manage pulse width, timing, and rail pressure for drivability, smoke control, and EGT management.
Will my stock CP3 keep up?A healthy stock CP3 may be marginal. For best results, pair with a higher-output CP3 and a quality 150–165 GPH lift pump. See our CP3 pumps and fuel system pages.
What’s included in this set?Six (6) new S&S Diesel injectors built with 60% over SAC nozzles, flow-matched as a set. Install kit items (feed tubes, lines, gaskets) sold separately.
Do I have to replace the injector feed tubes?Highly recommended on any injector job. Fresh tubes ensure proper seating and help prevent leaks. We offer kits that include new Bosch tubes.
Is this street-friendly?With correct tuning and supporting fuel/air, many customers daily-drive 60% over setups. Monitor EGT and keep maintenance on point.
