Hi folks, I've got a 57 plate 123d m sport. I'm thinking of getting the ecu re mapped. So the question is...... 1 is it worth it? 2 what gains do I get? 3 will it improve mpg? Thanks in advance Jay

Hi all, I have just bought a 123d M Sport 3 door hatch. Just thought I join to say hello and pick your brains lol Jay
