I would expect the car to pick up more than 2-3mph in that amount of time not counting any gear spacing improvements.

Off the line the DCT may suffer depending on what form of LC we get. Good drivers can easily beat the SMGII off the line (us version).
This is what my simulations showed using some optimization and some speculation on the DCT gears. It will very likely take a third shift to get through the 1/4 in DCT whereas the MT only takes only 2 shifts. I show about a .28 s time difference and only a 1.1 mph trap improvement. However, this is entirely consistent with the much more impressive 10.6 vs. 10.0 seconds predicted for the 0-100 mph times.
