Owners of Ford’s high-performance diesel, the Focus ST diesel, can now unlock even more performance with the launch of mountune’s m460D power upgrade kit. The m460D kit includes an OBDII flashing cable, dongle, performance calibration and a mountune badge. With a focus on real-world performance, mountune’s calibration is claimed to reduce the 0-60mph time by 0.7 seconds and cut the 31-62mph time by 0.5 seconds.

“mountune has been producing market-leading power upgrades for over a decade and this is the first time we’ve been able to unlock the potential in a ST diesel product”, says David Moore, Global Brand Manager.  “The standard Focus ST diesel is a great base car, but with the m460D kit installed we’ve been able to make it smoother, quicker and generally even more fun to drive.”

Power output is increased by 20 bhp while torque is improved by 37 ft lb resulting in a significant performance improvement while retaining the correct DPF regen strategy. The kit can be installed at home, but mountune encourages customers to have it fitted at the team HQ, where the company builds its BTCC and Rallycross engines.

Priced at £429 for DIY installation or £350 for installation at mountune HQ in Brentwood (due to the fact that a DIY fit requires an individual dongle and cable) m460D, which is only available for cars with a manual transmission, is, according to mountune, one of the most affordable ways to add both performance figures and real-world ability to a Focus ST diesel.
