ive had my 1.6 remapped, i couldnt be happier, its made a real difference! i used to have a 1.8 car (not a focus, so i try to forget about it lol) and my focus now drives the same, if not more nippy! my parents have a 2.0l turbo diesel BMW and i managed to keep up with it in a race! my cars alot more fun and easier to drive since i had it remapped, HIGHLY recommended!!
