I Just had my car remapped & the results are brill. I work in Derbyshire so have to use the M18/M1 every day & now have no problems overtaking all those troublesome BMW & Audi drivers who sit in the middle lane. No but honestly the results are ace - my car is now much more smoother & diesel consumption has gone down. I would highly recommend having your car remapped, if only to feel like a girl racer for a day.
