Description

The mountune m365 power upgrade for the manual and automatic Mk4 Focus ST takes power and torque to another level, delivering effortless performance, even more drivability and a soundtrack that really befits Ford's flagship ST model.

Utilising the required, carefully engineered hardware upgrades to reduce a substantial bottleneck in the exhaust system, the m365 calibration fully optimises this available headway and increases peak power to 365PS, with torque raised to a substantial 560Nm.

As with all mountune upgrades, it's had to pass our own stringent durability testing criteria, which included tens of thousands of miles and many months accumulating extensive data based on different driving scenarios from road to track and when used on different fuel octane ratings to ensure engine robustness, so you can still have complete peace of mind.

Careful attention has been paid to ensure that whilst brutally fast, m365 is still compliant, refined and useable on an every day basis - equally, the way in which the torque is produced and spread across the rev-range means you'll get instant response regardless of where you are in the rev-range and a top end that's rewarding to rev.

As with our previous m330 calibration, m365 is applied using our mTune SMARTflash app, so programming your ECU is also an easy DIY job; 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.

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.
