i've had 3 cars remapped no issues, one car I put a plug in box on for a week and it never drove right since.
everyone will have their own story, but mine is that a plug in box effectively wrote off a car for me, 3 remaps and never had an issue, although I tried a sport map and it did finish off my already worn clutch, but that's me driving like a tit more than the map imo
