The smart flash upgrade is very easy to install and when i had a question there was also a quick answer. In the app you get the 200 version and your old version, so you could bring the car back to 150 hp. More fun to ride and also in comparison with other tuners it feels save for your engine.
The m200 Mountune calibration transformed the engine by making it both more refined in the lower revs and more eager in the higher revs. The gain in torque and power is clearly noticeable and more importantly, it is significantly better distributed across the rev range than before. All in all, this upgrade compliments the driving qualities of the Ford Focus, which now feels both more relaxed in real life and sportier when needed. Installation was quick and pretty straightforward through the SMARTflash app, so thumbs up for the Mountune team.
The m200 upgrade has transformed my car while remaining fuel efficient and reliable at the same time. Would recommend to everyone owing a Focus with the 1.5 petrol engine.
