I've also heard that MDS is not on the 6.1. But what is the reason it's not on it? Is it technically not feasible or just DCX chooses not to?

Regarding the 6 speed, I would say that is my number one priorty too. I've been impatient about when DCX is going to begin taking orders, but now I'm kinda wanting for DCX to wait until Ford and Chevy tip their hands on what they'll be offering in the Mustang and Camaro. However, if DCX starts taking orders before we hear any news from the other two and I can get the 6.1 and the 6 speed in the Chally, then I'll do it. If the choice is an R/T 5.7 with a 6 speed, then I just might do it. If the 6 speed isn't offered in the Chally, then I'm probably going to wait.
