I was going to have mine recoded whenever I brought mine into the dealer but have not had the need to yet. So far, 4800 miles and very used to hitting the ASS button and selecting sport+ to the point where it's just a natural part of starting the car. At this point I probably will forget to ask them to recode it whenver I do bring the car in for something.
