try 1-800-FOR-Mercedes (I think thats the number).

That is the number for Mercedes Benz USA. Perhaps they will be able to fax you what you need, or direct you to where you need to go.

If you havent already searched, try searching for performance chip as well, maybe one of the chip programmers, like PAD, or Superchips can enlighten you as they can reprogram the car and remove the Limiter.
