The ZERONINE Design Stage 01 275PS power upgrade for the Mk3 Focus ST releases the maximum achievable power and torque from the potent 2.0-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 ZERONINE Design.

As with all ZERONINE Design 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 275PS, whilst torque is uplifted to 330FtLb 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.

The FLASHlink 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 FLASHlink 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.
