SC 91 Tune and MDS

[MagnumRT2SRT8]

Perhaps a stupid question, but if I'm running the Flashpaq 91 tune does this interfere with MDS? Also, if anyone has gone to meatier tires than stock on the 18 R/T rims, how has it affected handling?

MDS seems more active with the Torque reduction of Superchips, but the 91 tune doesn't affect it AFAIK...

I have KDW2 255/55r18 on my RT. Alot meatier (SC tiresize set to 28.25)... The only complaint about these wider tires is they will track(follow) uneven road surfaces more and slightly jerk over pavement seams. Otherwise the fatness rocks!

THanx for the info. I have a long thrip this weekend and I wanted to get some decent mileage! I think I am going to go with the meatier tires when these ones burn off. With No ESP its gonna be a lot sooner than I thought!

91, reduced TM, my MDS stays on past 90MPH, kicks in at 19MPH.

Long trip, run your tires at 36 psi cold.

I think the 255/55 's look better, but for what its 's worth I've had the 245/55/18 KDWS and the 255/55/18 KDW2'S and thought that the 244/55's actually handled better, just felt planted to the road better. Thes are BFG's, so I can't comment on other brands. SC 91 tune should slightly help with mileage.
