Making more output from a turbocharged engine has long been the lowest-hanging fruit of the tuning industry, especially when reflashing an ECU with a new map can easily make more power. Sometimes much more power.
That’s not the case here. The Ford Focus RS Mountune upgrade, available in Europe, gets only modest stated increases—20 horsepower and 26 lb-ft over the standard RS, a car rarely criticized for being short of firepower but, crucially, it’s sold with Ford’s full approval and warranty support.
Mountune has a long history of extracting more power from production cars and working as a specialist race-engine builder, but in recent years it has become Ford of Europe’s go-to arm for tuning upgrades.
As well as an ECU reflash, the RS375 kit brings high-flow silicone intake tubing, an upgraded recirculation valve, and what’s described as a sound suppressor to cut down on noise from the increase in boost. Most important, it also comes with Mountune badges to ruin the day of mere Focus RS drivers.
Any fears that such a modest increase in power and torque won’t be detectable are nullified as soon as you start to drive the RS375. These are big horses, the sort that get the Jockey Club ordering blood tests.
The Mountune-tweaked car feels instantly keener and brawnier, pretty much across the entire rev range. We suspect the quoted gains are deliberately conservative to help appease Europe’s insurance companies.
