We just got an 2008 Aspen with the 5.7 and MDS. I noticed my torque app does the same thing you are describing, mileage is way high when in MDS. At least my Aspen says "fuel saver" on top of the average economy display when in MDS so I can tell when it's in MDS. I also found the Aspen's average economy read low when compared to a full tank fill up. It said 17.2 MPG for a long trip and I actually got 18.1 hand calculated. speedometer was right on GPS speed. That was at 60-72 MPH average and in 32-35 degree temps with two mountain passes. It seemed to go into MDS more often and longer at 72 then at 65, I don't know why, the RPM there is about 2200 so maybe it just makes more torque. Around town it seems easy to keep it in MDS mode and get 17 MPG so I don't know where the EPA 13mpg rating comes from except their stupid test.

It is sad that Scanguage and Torque can't figure out the MDS mode and correct the economy. I have a feeling the onboard MPG gauge also isn't adjusting right but hopefully not doubling MPG like the Torque app seems to when in MDS.
