Since we have been allowed to call a Smart our own since yesterday, we are somewhat concerned about whether we might want to have it chipped. The car is mainly moved by my mother (had already written a Fred a few days ago), but since I will also use it now and again and someone else, just this consideration. Now my real question. Is the 451er 45Ps cdi suitable for a chiptuning?? We are actually also satisfied with the performance, clear he is not a rocket but in the city he is a really good, small flicker and is also fun (especially in the current weather), but a little more it may be. Of course the engine should also perform its service in the long term after the chipping, no desire for a motor damage after 10tkm. If the engine is now suitable for a chip tuning, would the 2nd question be, until how much horsepower could one go, that the engine still remains durable? I thought about 60-65Ps, Is that possible? I mean with 65Ps would certainly push forward properly with the weight! With such a car you can notice almost every multi-Ps. Do you know good manufacturers that offer a serious tuning? Provided it is really worth it. Thank you! Here is another picture of the small one:
