I have a VW Polo 6r 1.2 TDI 55KW. The problem is its acceleration. I’ve heard that chiptuning could solve it, but I was wondering if it was legal in BELGIUM. I know there are different types of chiptuning, but I think I have to choose the lowest because the others are bad for the car and illegal too. I am not excepting a much better performance, if I was, I would have bought a Golf 6 or something like that. So, anyone who can help me? (I can speak Dutch too, so you can answer in Dutch if it’s easier for you)
