It's time you started something amazing.
From the moment you start a mountune M400-equipped Focus RS, you know you're behind the wheel of something special; relentless torque, top end power and added character await you... all with the reassurance of being engineered by the Ecoboost engine experts.
The M400 power upgrade fully optimises the potent performance available from the 2.3-litre EcoBoost, whilst running the standard turbocharger.
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.
Outright acceleration is equally improved, dropping the dash from 0-60mph to just 4.2secs!
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 (via future firmware update) and dyno mode, to disable/enable the RDU (Rear Drive Unit) for easy dyno testing, directly from the handset.
