2nd Apr 16 Focus ST Diesel Well I was very sceptical about the Tuning box and peddle box but decide to go for it as they offer a 14 day money back guarantee and would have had no hesitation claiming for it. It’s completely transformed the car making it a pleasure to drive and pretty nippy, more responsive not just from junctions but all the way through the box. This is how the car should be. Although apprehensive about fitting there dead easy with instruction and photos showing every step of the way. Try it what have you got to loose.
