Tune Changes Required: Upgrading to the FX-170 requires calibration adjustments. Be sure to make these changes before operating the vehicle to avoid any potential damage or voiding of the warranty. Spool Performance offers calibration data to your tuner and can connect you with tuners experienced in working with these pumps. Proper tuning is essential to maximize the performance of the FX-170 setup.

Low-Pressure Fuel Pump Consideration: Upgrading the low-pressure fuel system is critical to maintaining the durability and functionality of high-pressure pumps and injectors. Inadequate low-pressure fueling can cause damage, resulting in warranty voidance. Ensure your fuel system build includes proper low-pressure upgrades to avoid any potential issues.
