The mountune m260 power upgrade for the Mk8 Fiesta ST takes performance to a whole new level, quite literally, releasing up to 260PS and 365Nm from the ST's 1.5-litre 3-cylinder EcoBoost engine - and all whilst still retaining the factory GPF and catalyst.
The additional torque output is delivered across a wide spread in the rev-range which translates into effortless drivability and totally transforms the overall driving experience and fun-factor. By removing some of the inherent bottlenecks in the OE hardware, the optimised calibration boosts peak power to between 250-260PS and makes it equally rewarding to rev!
Installation couldn't be simpler, as the m260 calibration is supplied on our mTune SMARTflash app which allows for quick and easy calibration changes in minutes. All you need is our app, the supplied Bluetooth OBD interface and your Smartphone; no laptop, no wires, no handsets, no problem!
The latest version of SMARTflash also provides additional functionality, such as: fully configurable gauge displays using the OBD data-stream, comprehensive data-logging and a built-in performance meter, too.
m260 SMARTflash also includes plenty of user choice as standard, with three specific performance calibrations, plus two companion calibrations (standard and anti-theft) which are supplied with the following features:

Please note: in order to update to our SMARTflash V2 release, you will now need to download our partner app, ECU Connect - once 'mountune' is selected within the tuner menu of the app you will have full access to the SMARTflash V2 features.
For assistance setting up and installing SMARTflash V2, please refer to the user guide, here.
Important: In order to achieve and maintain performance and reliability, the m260 upgrade should be used in conjunction with the hardware listed below and should only be used with 97RON+ fuel. If a lower octane rating of fuel is the only grade available we recommend switching to the m235 calibration which can be used on normal unleaded fuel reliably in all scenarios.
Recommended m260 hardware:
