FAQ

Yes. These hybrids require a steady ~65 PSI at the rails for proper function and warranty compliance. A regulated return eliminates the stock dead-head and stabilizes pressure under load.

At minimum: blue-spring regulator upgrade, less-restrictive banjo bolts, fresh standpipes/dummy plugs, strong HPO system health, and appropriate custom tuning. For higher power, add head studs and airflow mods.

Custom calibration is strongly recommended to match the 285CC flow, turbo, and fuel system. It ensures drivability, EGT control, and reliability.
