Mountune has been fiddling with Ford engines for as long as we can remember, and they specialize in working on the EcoBoost mills inside the Fiesta and Focus hot hatches. Some of their recent highlights include a 232-hp tune for the latest-generation Fiesta ST and an insane 684-hp configuration of the engine powering the old Focus RS. Now, the time has come for the not-for-America Focus ST to get a healthy power bump.

It unlocks 50 horsepower and 70 pound-feet (95 Newton-meters) of torque, with the 2.3-liter gasoline turbocharged four-pot now producing a respectable 325 hp and 380 lb-ft (515 Nm). With the tuner’s m330 upgrade package in place, the new Focus ST is only 20 hp shy of the Focus RS and it actually has an extra 30 lb-ft (41 Nm) over the AWD hot hatch.

With the m330 package installed, Mountune says the VW Golf GTI competitor needs just 5.2 seconds to complete the 0-60 mph (0-96 km/h) sprint, thus making it about half a second quicker than the standard Focus ST equipped with the six-speed manual transmission.

The upgrade kit costs only £599 (about $690 at current exchange rates) and comes bundled with a 12-month / 12,000-mile warranty. Interestingly, it can be easily installed by the car’s owner as Mountune’s adapter plugs into the OBD. There’s a smartphone app allowing the Focus ST driver to activate the power upgrade or revert to the standard configuration of the EcoBoost engine. A third option is Anti-Theft, which completely immobilizes the car.

For those who would rather have a more powerful Focus straight from the factory, there are rumors of a new RS. However, the engineers have yet to sort out the issues regarding how to make the engine comply with more stringent emissions regulations.

20th March, Brentwood. Owners of the Mk4 Ford Focus ST can once again join the mountune family thanks to the release of its latest upgrade – the m330 package. Extracting even more out of the award-winning Focus ST, the m330 package builds on the success of the m225 and m235 Mk 8 Fiesta ST SMARTflash technology. Through the use of the market leading technology, mountune has been able to deliver significant upgrades in usability and performance whilst guaranteeing an OEM+ feel.

All power upgrades developed by mountune undergo a rigorous testing and development process, akin to that of an OEM and the m330 package is no different. Once again, its dedicated team of tuning professionals have delivered a package that stretches the boundaries of the Mk4 Focus ST, putting the driver firmly in control.

Both power and torque have been taken to a new level with the m330 package – equating to an increase of 50 PS to the peak power output & an increase of 95 Nm of torque. mountune’s vastly experienced engineering team have worked hard to develop a sophisticated calibration that is not solely restricted to increases in performance. Using the same technology as the m235 Mk8 Fiesta ST kit, the m330 package incorporates no-lift shift optimisation, making smooth and precise lift-less gear changes easy, as well as enhanced exhaust overrun to create an optimum driving experience.

“We’re delighted to finally launch the m330 package, enhancing power and performance to what is an already great car,” explains Alec Pell-Johnson, Director of mountune performance. “Both the m225 and m235 kits have been hugely successful since they launched, with customers loving how easy it is to change the calibration of their car direct from their smartphone. SMARTflash is the future of calibration upgrades and we are looking forward to seeing how our customers receive our latest upgrade for the Mk4 Focus ST.”

Customers can take advantage of mountune’s market leading mTune SMARTflash app, allowing them to install the latest calibration from the comfort of their home. Using nothing else but the mTune SMARTflash app on their smartphone and the supplied Bluetooth OBD interface, Focus ST owners can completely change their much-loved vehicle.

The intuitive SMARTflash system has been designed to make a selection between different calibrations simple and fast, giving users the freedom to change the vehicle to suit their needs and moods. The new app also enables mountune customers to effortlessly update their vehicle with the latest calibrations directly from mountune and includes a convenient VIN and calibration ID reader.

Three distinct calibrations are included with the m330 upgrade, providing users with a range of practical options. The m330 Performance calibration delivers the previously mentioned power and torque increases alongside a more aggressive launch control strategy and enhanced audible exhaust output in Sport/Track modes. The other two calibrations are Stock Performance, which returns the vehicle to its standard configuration and Anti-Theft, which fully immobilises the vehicle.

Specifically engineered to work alongside the SMARTflash calibration upgrade and completing the m330 upgrade package, mountune’s high-flow panel air filter ensures that owners can extract maximum performance from the 2.3 Litre EcoBoost engine.

The complete m330 package includes:

  • SMARTflash EVI Bluetooth OBD adapter
  • mTune SMARTflash app, available for both Android and Apple
  • No-lift shift optimisation and enhanced exhaust overrun
  • Slippery mode is turned into quiet sport mode
  • 3 useful calibrations: Performance, Stock and Anti-Theft
  • High-flow panel air filter
  • mountune badge
  • mountune zip-up shell case
