EC quality has been nothing short of IDEAL!!! Their tuning is actually fully evaluated by FCA engineers! My TiSport has no tranny issues and the ZF unit is profoundly capable. For the occasional power blast a nom issue IMHO, if you track the car at high levels???? as would be the case anyways. If you drove my car, you would just think it was a better Stelvio that shifted better, had 80-110 more HP and felt like it was factory perfect.
