Once upgraded to the MR375, power increases from either 305PS (standard) or 350PS (from the RS500/MP350), to 375PS at 6700rpm and torque is raised from 440Nm (standard) to 550Nm at 3,500rpm.
The MR375 also produces performance returns of 0-60mph in 5.0 seconds, a 0.9 second improvement over the standard RS, and 0-100mph in 11.3 seconds, continuing on to a top speed of 165mph.
The power uplift that came with the RS500 from the factory is the power upgrade subsequently sold to standard RS customers in the form of the MP350 kit. The hardware found on the RS500 is also identical to this, therefore you need the same additional hardware as stipulated below.
The Mountune Racing MR375 package is based on the hardware from the market-leading Focus RS500 / MP350 Mountune upgrade but additionally includes:
This upgrade can be fitted to any Focus RS or RS500, and comes with a minimum 12 months/12,000-mile warranty against manufacturing defects on all parts fitted.

As part of the calibration update process the original vehicle ECU will need to be returned to Mountune. Please note: Mountune Racing parts do not benefit from the same warranty arrangement as Mountune Performance parts and as such fitting MR parts may invalidate part of your base vehicle warranty.
