I've had my truck for a little over two months, and I'm having the exact same shudder with the MDS.

I will say, if you use 93 Premium gas, it is MUCH less noticable. Decelerates smoothly and kicks into MDS barely noticable.

Tried putting 89 in it a couple times and it felt horrible/shuddered like hell. Feed your hemi the best and it will treat you well.
