You want smooth? How about 500+ ft/lbs at the wheels by 2,800 rpm? 700+ ft/lbs by 4,500 rpm and still climbing. That, my friend, is smooth. Forget down shifting. Just ease down on the throttle and watch the little Mustang slide backwards as the rpm builds.
Every now and then, owning a science project has it's benefits.

As for the Evo, one of the guys at work has a 2005 MR. It cost him more than my SRT and could not get around it until after he added software mods, swapped out the exhaust, and increased the boost. He's now run a 12.9 to my 13.2 at the same track.
