The mountune m330 power upgrade for the manual and automatic Mk4 Focus ST releases the maximum achievable power and torque from the potent 2.3-litre EcoBoost engine without significant hardware changes, substantially yet safely raising power and torque output; improving outright performance, drivability and fun, whilst also adding a host of functionality, unique to mountune.

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 such as in-cylinder pressure and other key metrics all based on different driving scenarios from road to track and when used on different fuel octane ratings to ensure engine robustness, whilst retaining all safety parameters, so you can have complete peace of mind that you're not just buying the best upgrade for your Focus ST, but also the most robust aftermarket calibration, too.

Peak power is increased to 330PS, whilst torque is uplifted to 515Nm but, as can be seen from the power graphs, it's the substantial increase throughout the rev-range and the way the torque is delivered that completely transforms the driving experience.

Working together with industry leading software and hardware teams has enabled the very latest technology available to be incorporated, taking mTune - and making it a whole lot smarter!

The mTune SMARTflash app allows you to easily DIY install and update calibrations to your ECU using nothing more than 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.

m330 SMARTflash includes three calibrations, with unique functionality:

• m330 performance 

	Increased power and torque (330ps / 515nm)
	More aggressive launch control strategy
	Enhanced audible exhaust output in Sport / Track modes (manual only)
	Custom Track Mode (recalibrated wet-mode for track settings minus pops and bangs)

• Stock performance
• Anti-theft

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.

For assistance setting up and installing SMARTflash V2, please refer to the user guide, here.

The m330 calibration has been fully optimised to utilise the mountune high-flow panel filter, which allows the engine and turbocharger to work more efficiently, as well as improving induction noise.

UPDATED: m330 can now be used with the mountune high-flow downpipe sportscat without emitting an EML.

m330 supports all known regional variations both manual and automatic models and as it can be installed and removed anywhere in the world, at any time yourself, you could say the power's in your hands, quite literally!

Please send us your VIN to check compatibility, info@mountune.com.
