in my opinion, MDS is absolutely pointless. You will never get 4cyl in city. And as far as freeway, on my 2008 avalanche if i barely touch the accelerator it kicks back up 8. Bacailly it only is ever at 4 when you are not touching the accelerator and doing about 60 mph.... That or the avalanche is busted. Who knows.

The MDS turns on around 45 for me, and I've had it stay on for cruising as high as 85. I get some acceleration without the MSD kicking off (but press that pedal a little too hard or go on an upgrade and it comes right off) I cruised 50 miles on the NJTP with the cruise control on and MSD engaged the whole time... I reset my MPG and after the cruise I was getting almost 28mpg.
Not too bad for a 370+hp V8
