FPM375 > M400 Power Upgrade Kit - RS

The mountune FPM375 > M400 power upgrade fully optimises the potent performance available from the 2.3-litre EcoBoost, whilst running a standard turbo.

This option is for customers already running our FPM375 Focus RS upgrade and that want to upgrade to M400 specification.

Utilising a selection of fully proven mountune hardware - some of which endorsed by Ford themselves, to help lower charge temperatures, improve pressure drops and remove back-pressure, means the engine is now able to operate more efficiency, allowing the impressive peak 400PS and 560Nm power and torque output to be more safely, and reliably achieved.

As with all mountune power upgrade kits, M400 is available as a complete power upgrade from standard, but equally continues the modular approach, allowing owners to add the required hardware in stages, before culminating in what’s undoubtedly the most well-rounded performance upgrade available, that retains the standard turbocharger.

From both years and hundred’s of thousands of miles of product development and durability testing of the RS-spec 2.3-litre EcoBoost engine, mountune’s knowledgebase is unequalled regarding the engine and also, the calibrations strengths and limitations.

It’s from this rich test bed of data that M400 has been formed, pushing the envelope of performance as far as possible. Upgrading hardware that would otherwise be beyond its safe operating point to ensure maintainable, repeatable performance and calibrating to retain the maximum possible drivability, and ultimately, reliability.

Like previous RS releases, the M400 mTune also includes an anti-theft mode and dyno mode, to disable/enable the RDU (Rear Drive Unit) for easy dyno testing, directly from the handset.

Please Note: The warranty of the vehicle being updated with this upgrade may be affected. The M400 upgrade kit is not Ford-endorsed. 

To maintain any warranty provision otherwise entitled to you, and to ensure correct operation, reliability and performance figures quoted are achieved, calibrations loaded via an mTune handset must be installed together with the correct mountune® hardware.

Support is not currently available for vehicles in Asia-Pacific, this will be added in the next firmware update.
