Why Choose the FX-170 for Your M276?

Tune Requirements:

Calibration Required:

• The FX-170 requires ECU calibration changes to function correctly. Do not start the engine without updating the tune, or it may cause internal damage and void your warranty.
• Spool can assist your tuner with calibration data and connect you to trusted tuners experienced with the FX-170 setup.

Low Pressure Fueling Advisory:

Don’t Neglect Your LPFP

• A properly matched low-pressure fuel system is vital for DI fuel system longevity. Insufficient LPFP support can lead to piston scoring and bore damage in the HPFP—warranty-voiding issues easily avoided with the right setup.
• Pair your FX-170 with a Stage 3 LPFP upgrade for maximum performance and safety.
