I also saw this along with another one that supposedly hooks to a sensor and adds 22 horsepower at the rear wheels. No one bid on it, which leads me to believe that it is a new variation on the magic "black box" that the automobile companies don't want you to know about. In my opinion, if it were that easy to add power to the engine, with no adverse side-effects, Mercedes would have done it already. If anyone has tried one of these devices it would be interesting to hear their experience.
