I'm sure it does. If I have the space I can go from 0 to 25 mph without touching the gas pedal. I attribute a lot of that to the gearing (3.73) and the power of the engine itself. One annoyance, the flywheel is so heavy that I have to delay my shifts so the rpms can drop down enough.
Practically every performance LS motored car has received a normal flywheel weighing half of what mine does. The dual mass was strictly for comfort. They come loose after a while causing a shake on shut down, which I have. GM didn't think through a lot of the decisions they made when building this low production car, most of which was corrected in the new CTS-V.
