I cant make up my mind which to get. Ive been offered a decent Tuning Box for £140 but am wondering if it would be better to get a Remap which costs about £300 and which some people say is better. My car is a BMW 320D. My friend who is an electronics engineer says a good Tuning Box is almost as good as a remap and at £160 less i'm inclined to go for it. I would appreciate some advice here.
