I have been curious as to how much mileage difference the MDS makes if any. I am getting a little annoyed with the "kick" from it going from hungry v8 to 4 cyl. Anyways I do a lot of city driving so I was curious as to what you guys were getting before and after.:smileup:

Hi, I tried the MDS on and MDS off test for a tank of fuel each and in town didn't see enough of a gain to recommend keeping it on. But on the highway it did add a significant gain. I would get a Diablo and kill it since you have a 2010 and the tuner will give you many more value adds!
