The mountune FPM375 > m400R Power Upgrade Kit optimises the 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 m400R 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, m400R 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 hundreds of thousands of miles of product development and durability testing of the RS-spec 2.3-litre EcoBoost engine, mountune’s knowledgebase is unrivalled regarding the engine and also, the calibration's strengths and limitations.
It’s from this rich test bed of data that m400R has been formed. 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.
The m400R mTune also includes a host of new features and functionality (see below) as well as an OE power and fuel economy calibration.
Please Note: The warranty of the vehicle being updated with this upgrade may be affected. The m400R 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 a forthcoming firmware update.
Wow what a difference this makes best mod I have ever done plus the guys at mountune are a pleasure to deal with would highly recommend this it’s amazing the power and the sound makes is breathtaking, what are you waiting for?
Just had the M400 installed along with the forged engine I modification. Early days as the car needs to be run in for 1000 miles but first impressions are it feels good very smooth.
What can I say about this upgrade it’s pretty damn fantastic, it really brings the rs alive and the the sound is a symphony even my misus loves it, thank you mountune another very happy customer
