The mountune m200 power upgrade for the automatic Mk4 Focus ST-Line releases a substantial, but safe uplift in useable day-to-day power and torque from the 1.5-litre 3-cylinder EcoBoost engine.

Peak power is increased to 200PS at 6,000rpm making it much more eager and rewarding when you want to use the full rpm-range, but there's up to 60Nm of extra torque that's accessible from as little as 2000rpm across the full engine range that you'll feel everyday, getting you through the gears and pulling you out of corners that much more effortlessly.

Whilst torque is uplifted to a peak of 285Nm - due largely to the smaller turbocharger found on this model, the spread of the uplift is across the entire range, which makes this a particularly enjoyable upgrade for those that use their cars daily as it transforms the driving experience and your enjoyment, regardless of how it's being used.

We've also developed this upgrade to be fully optimised with 95RON fuel plus, it's compatible with both 150PS and 182PS base models with a manual gearbox.

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 the app also provides data-logging, a fault code reader and a performance meter - for additional peace of mind, there's also an anti-theft option than can be easily installed to immobilise your vehicle.
