To have it Tuned u need to connect it to the Star Diagnostics System. Its with all MB Workshops although they wont let u confiqure ure car. Ahura Car Care does all my Cars. I think hes the best there is. Take it to him and he will let u see the Diagnostics and change all the settings for the Engine. Although be warned its an EXPENSIVE Work. I'm not sure what the cost is but none the less.
