I never understood why they didn't put the Fiest ST engine into this car for those of us who enjoy driving but can't justify the expense (including fuel economy) of the Focus ST. Since I purchased my car I had hopes that mountune would come up with this package. Even having no experience in these matters, the install was trivial and the result was exactly what I was looking for. Smooth delivery of torque and power giving the car finally the sport feel it deserves. Now I just need to adjust the awful pedal positioning (to be able to heel and toe) and I will be good to go.
The smart flash was extremely easy to use myself, the difference is very noticeable at all speeds in any gears, a lot more pulling power and much better at getting up to speeds
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.
