Mountune succeeded in boosting the Euro-spec Ford Focus ST to 330 metric horsepower last year (see video), and has now achieved even more with the same hardware.
The new kit, which is named m365, costs £1,838 and includes high-flow exhaust components, a sports-grade catalyst, a particle filter, a better air filter, and an ECU tune. It is largely identical to the m330 package released earlier except for the software, so owners of the older tune may order a software upgrade for just £99 and get all the benefits of the new version.
Once everything is installed, the stock EcoBoost 2.3 four-cylinder turbo produces 365 PS (360 hp / 268 kW) and 560 Nm (413 lb-ft) of torque. The tuner provides no launch time measurements, but we expect the boosted Focus ST to be much faster in a straight line than the 5.7 seconds the stock car is capable of.
