I'm not totally up on this stuff, but I do remember seeing a video on this site where the throttle opening was actually being reduced by the PCM during shifts (and you can bet timing was being pulled too). On the aftermarket tunes, I wonder if they have totally removed the torque management on the 6-speeds, or just reduced it. Seems like the transmission should be able to take it (Viper trans right?), but maybe it's there to prevent burst knock, or to protect the rear differential.
I'd think that the reason 6-speeds don't have MDS is that 6th gear is so tall that there just isn't much to gain by shutting off cylinders.
