The new mountune m330 power upgrade for the 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!

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
	Custom Track Mode (recalibrated wet-mode for track settings minus pops and bangs)

• Stock performance
• Anti-theft

In addition, the SMARTflash app, which is available for Apple and Android users, also allows for easy future calibration updates and includes a fault code reader, plus a handy VIN and calibration ID reader as standard.

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.

m330 is available in two versions that support all known regional variations (excluding automatic transmission - support coming soon) 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 note: the m330 in currently unavailable for Asia-Pacific specification cars, due to different emission standards. Please send us your VIN to check compatibility, info@mountune.com.

The m330 is not transferable from car to car.
