mTune SMARTflash m365 Upgrade [Mk4/Mk4.5 Focus ST]

The mountune m365 power upgrade for the manual and automatic Mk4 Focus ST takes performance to another level, delivering up to 365PS and 560Nm from Ford’s 2.3-litre EcoBoost engine.

Utilising carefully engineered hardware upgrades to remove key restrictions in the exhaust system, the m365 calibration fully optimises the available headroom, delivering effortless performance, enhanced drivability and a soundtrack that truly befits Ford’s flagship ST model.

As with all mountune upgrades, m365 has undergone extensive durability testing, including tens of thousands of miles and months of data collection across a wide range of driving conditions, from road to track and across different fuel octane ratings, ensuring engine robustness whilst retaining the vehicle’s safety parameters.

Performance

Peak output increases to 365PS and 560Nm, with the additional torque delivered across a broad rev range for instant response and effortless performance in any gear. Despite the significant increase in performance, m365 remains refined, compliant and perfectly suited to everyday driving.
