I've had mine since the end of Jan this a year, a 2017 version with ACT. It is a good engine and as said it can provide good MPG on longer journeys. My work run of 7 miles averages around 35mpg with hills and plenty of stop/starts. Had it remapped a few months back and it feels even better, overall loving the car.
Hows is the ACT after the map?
And how much an increase did you see on bhp?
I am going for a remap myself as soon as it is out if warranty but haven't heard anyone mention if the ACT works the same or different after a map.
