I have had no problems with DBW at all. Never experienced the "sticky throttle" problem. I drive with the sport mode on all the time and, aside from the occasional rough shift from 1st to 2nd think it's great. I have seen many posts where people are advised to use normal mode in heavy traffic and sport in all other situations. I tried that for a while, but the difference in the throttle mapping was just too much for me to get used to. I tended to "bog" the engine in normal mode because of the large difference in throttle/engine response. You just have to keep a very light foot on the throttle or you are in danger of sticking your front in some one else's rear.
