I went to my local "rice" shop, and they said that it would be difficult to get a dyno run on the car unless you can shut off the ABS and Traction Control.
I'm not too sure what kind of dyno they had, but the guy was pretty adamant about not dynoing my car.
Are there particular dyno machines that can be used to dyno an MB? If not, how do you go about properly getting a dyno run?
