Mountune updates its Ford Fiesta ST power mod

Mountune has released a new version of its M225 chip meant to boost the engine performance of the 8th-gen Ford Fiesta ST.

Called M235, the new chip enhances the output of the car’s 1.5-liter turbo engine by a further 10 hp (7.5 kW) and 10 Nm (7.4 lb-ft), bringing the total to 235 hp (175 kW) and 350 Nm (258 lb-ft). Just how it impacts the acceleration remains to be seen, but ‘hardly much’ seems like the obvious answer.

As a nice bonus, you can fine-tune the engine output using a dedicated smartphone app. Paid options include a new cold-air intake system and a sports-grade air filter.
