Ford tuning specialists Mountune have released the “m225” package for the current Fiesta ST, targeting those who want even more grunt from their compact hot hatch. Along with the new upgrade package, Mountune is also launching their also new mTune SmartFlash mobile app, enabling users to install and update the software on their vehicle through their smartphone.

The new m225 pack increases the Fiesta ST’s peak power to 225 PS, up from the standard 200 PS of the turbocharged 1.5-liter EcoBoost three-pot. More importantly, the new software allows the engine to deliver more torque both earlier and across the rev range, something that according to the tuner transforms the driving experience.

Mountune reckons the Ford Fiesta ST fitted with their m225 upgrade package is now capable of running the 0-100 km/h in less than six seconds, down from the factory 6.5 seconds, and cut a full second from the in-gear 50-100 km/h acceleration figure.


The company’s new mTune SmartFlash app is combined with the provided Bluetooth OBD interface. The selection between different setups is simple and fast, while the new mobile app also enables customers to update their vehicles with the latest calibrations straight from Mountune.

The new Mountune m225 package comes with three calibrations: the “m225 Performance” produces the full 225PS together with a more aggressive launch control strategy in the Sport/Track driving modes. The other two are Stock Performance and Anti-Theft, with the latter fully immobilizing the vehicle. The package also includes a high-flow induction kit, a Bluetooth adapter for the OBD port and the mTune SmartFlash app for both Android and Apple devices.
