      I recently had my latest vehicle (a ‘standard’ RS Edition) upgraded with Mountune’s M375 power upgrade package by the fantastic guys at FJRS. But as I wanted the mTune handset which facilitates easy future calibration updates and now had the correct hardware installed, I decided to upgrade the map to M380. Although this may not seem much on paper, the difference really is noticeable with the extra power delivered smoothly throughout the rev range right up to the red line. I have also just fitted a set of Iridium Spark Plugs (also supplied by Mountune pre gapped and ready to go) which are optimised for maximum performance and are one step colder than the original spark plugs. Because I have had a long association with Mountune (having previously owned three Mk3 Focus RS’s that have all had various Mountune products installed), it was an easy decision to make when deciding on what performance upgrades to install on this vehicle and I now look forward to having the M380 to m400R kit installed next at FJRS, when it is back in stock.
