Thanks everyone. I have already installed the light. There just seems to be a lot of times that I think it should kick in that it doesnt. I think the MDS engineers tuned it to be slow to work as to make it transparent to the end user. I would not mind to feel a little power loss on the highway if it led to better mileage. I was just seeing if I could force it in somehow once I reach highway speed.
What I do with my truck when I want it to go into mds mode is when I get up to around 60 with the cruise on I step down on it till I see the tach drop down then I let it settle back down to the cruise and the tach now sets on around 16 and the mds light is on and that is where I get the best mileage.
Hi guys it's my first post here, I have a 08 Ram Hemi and love it, with regards to MDS function , has anyone had any success reprogramming with "superchip" programmer. and get better performance, miliage and MDS function?
