Great service from Mountune HQ again. The MR300 tune is a map that works well within the safety perimeters of the cars capabilities, and when driving around town feels quite stock. It has a linear feel to it, smooth but quick acceleration throughout the rev range and gear box. Its definitely at its happiest in 4th gear at 5500 rpm where its just a beast! Coupled with all the bits that make up the MR300 pack and a Quaife differential, RS Clutch and Re-circulation valve which were of course fitted by Mountune, its a real treat to drive. All in all a quality product supplied by Mountune yet again, thanks guys.
Took under ten minutes, to flash tune to ecu , thanks, J.
Happy with service and very simple to install. Can feel the difference in the car a lot more fun to drive !
