MDS still working with bigger tires??
 
Need some help from you Hemi guys. My buddy is looking to do a lift and 32's and is wondering if MDS is still going to kick in. Hopefully there are some of you that have done this and can chime in.

My MDS still worked when I lifted and went to JK Sahara 18's and 255/70/18's.

Did it seem that the system was kicking into MDS mode less with the change to the tire size and rolling resistance? Or did it function just like with a stock set-up?

It functioned the same (unfortunately) MDS is useless. I get better milage with it turned off and a 93 tune installed! Ha
