M380 Power Upgrade Kit [Mk3 Focus RS]

The mountune M380 power upgrade utilises the hardware from our endorsed FPM375 upgrade and in addition, adds a Sound Supression Chamber (SSC) and our mTune handset. Power is boosted to 380PS from 350PS, whilst torque is increased from 470Nm to 530Nm (on overboost), which is enough to deliver a sub-4.5 second dash to 62mph!

In addition to the M380 calibration, the mTune handset also is supplied with two additional calibrations with bespoke audible optimisation of the mountune cat back exhaust.

An anti-theft mode has also been included.

In addition to the mTune, this performance kit also includes a mountune high-flow induction kit, uprated re-circulating valve, Sound Suppression Chamber (SSC) and two mountune badges.

      Massive improvement in 2nd & 3rd gear.

      Main improvement it 2nd 3rd gears, however Mountune needs to update their approved dealer fitting service lists as Cramlington Ford was clueless and very unhelpful, although BGT in North Shields as a fitting service, brilliant and quick.

      What I needed!

      The car has a better reaction and having had a bad experience with another programmer, I am finally satisfied with the result with the M380 Kit!
