The m225 mountune package for the Fiesta ST provides significant increases to both power and torque, without compromising the vehicle's safety or reliability.

The new Ford Fiesta ST has had its shackles removed by the latest mountune upgrade. The new upgrade, the m225 package, is being launched alongside the innovative mTune SMARTflash app, which allows users to install and update vehicle calibrations in minutes from their smartphone.

With nothing but the new mTune SMARTflash app on their smartphone and the supplied Bluetooth OBD interface, Fiesta ST owners can completely change their vehicle. The intuitive SMARTflash system has been designed to make selection between different calibrations simple and fast, giving users the freedom to change the vehicle to suit their needs.

The new app also enables mountune customers to effortlessly update their vehicle with the latest calibrations directly from mountune and includes a convenient VIN and calibration ID reader.

The ST's peak power has been increased to 222bhp with torque increased all the way to 340Nm, but that isn't the whole story. The 1.5-litre, three-cylinder EcoBoost engine now delivers torque earlier and across the rev range, completely transforming the driving experience with blistering acceleration.
