My first post on here, I have just purchased a 57 plate 123d in mint condition with low mileage, its a beuatiful car but I want it remapping after driving my mates 330d before and after he had his mapped, the difference was amazing. My question is who has had theres done on here and what type of results bhp wise did you see? big difference in driving? did you use emaps as thats who i think i will be going to.
sorry if there is a lot of questions I'm just in a bit of a rush before i go out
