OC Motorsport Focus RS MK3 Stage 3 MSD 420bhp High Torque Remap + 70bhp + 90NM

OC Motorsport Focus RS MK3 Stage 3 MSD 420bhp High Torque Remap + 70bhp + 90NM

MSD420 Package (up to 420PS)


This calibration is only suitable for vehicles with the following hardware modifications installed:

  • Uprated Intercooler
  • Turbo Back exhaust system with sports cat or decat.
  • High flow air filter

We also recommend the following items:

  • A stronger compressor bypass valve. Plumb Back or Dual 
  • A step colder spark plug grade is highly recommended. We recommend either:
    • These NGK
    • These Denso


This package increases the top end power of the 400 conversion, with a slight torque increase up to 580NM and extending the power up the rev range to 420PS.

The factory rev limiter is retained, as are all the temperature protection features carefully programmed in by Ford, such as power limiting if coolant, oil, exhaust or charge temperatures get high. The ECU will actively lower your available throttle opening and boost pressures as well as add fuel to cool things down until such time as the temperatures are back within safety parameters. Some tuners remove all this to achieve their power - Take care out there.


The package includes the supply and fitment of:

  • Evolution Chips MSD420 ECU calibration
  • Full Engine Management Diagnostics Check

Options Available:

  • Decat MIL Eliminated (For vehicle with a De-Cat fitted)
  • Launch Control RPM set-point options of 4000 / 4500 / 5000 rpm.
  • Stop / Start disable.
  • Eco shift light disable.
