FAQ

With appropriate fueling and tuning, S475 setups commonly support high-horsepower builds while the .90 A/R favors quicker spool with moderate injector sizes. Select injectors and supporting mods to match your target power.

Yes—this kit is designed as a complete, clean install on 2003–2007 5.9L trucks with the included intake, lines, clamps, and hardware for a tidy under-hood fit.

For best performance and reliability, we recommend a quality lift pump and, for larger injector sets, a higher-flow CP3 pump to maintain commanded rail pressure under load.

.90 A/R favors faster spool (good with moderate injectors/gear), while 1.0–1.10 A/R reduce drive pressure at high flow with big injectors and higher RPM usage.
