Fitting: mountune HQ only

The mountune mr500 takes the performance of your Mk3 Focus RS to the next level. Developed for the track, utilising the BorgWarner EFR twin-scroll turbocharger. As proven in multiple mountune Racing engine applications, the mr500 will transform your driving experience! With power output up to 500PS and up to 700Nm, this kit delivers exceptional performance.

Due to the increased cylinder pressures, this calibration should not be used on vehicles that have not been upgraded with forged pistons, steel con rods and that are using a colder spark plug. 99RON+ fuel is required to be used to maintain performance.

Adjustable RPM limit
Full-time launch control (no need to activate via the menu system)
