Helpful Notes
- Maintain a stable 65 PSI fuel pressure on the rails; a regulated return is strongly recommended for injector life and consistency.
- 225cc injectors pair best with an upgraded lift pump, quality filtration, proper tuning, and appropriate turbo/exhaust to control EGT.
FAQ
Do I need tuning with 225cc injectors?Yes—custom or appropriate tuning is recommended to match pulse width and manage smoke/EGTs, especially on towing or street setups.
Will the stock lift pump support these?Not reliably. We recommend a lift pump/filtration upgrade (e.g., AirDog DF-165) and a regulated return to maintain pressure and volume under load.
Are these drop-in for all 2003–2007 6.0L?Physically yes for 6.0L Super Duty applications. Always verify build year components (’03–early ’04 systems can differ) and follow proper install procedures with new seals.
Should I do head studs with injectors?For any tuned/225cc setup, head studs are strongly advised to keep cylinder pressure in check and improve reliability.
