DCT shift times
How quick are they currently in both auto and manual modes?
Will they improve with more dialed-in programming?
How does it compare to the PDK-S, which is even better than the regular PDK?
PDK-S is used in the GT3/2/RS.

That depends on how you define "shift time". By one measure, it is zero because the shift can take place without any interruption of power to the wheels. But many torque converter automatics can do this too.

These are loaded questions with dual clutch setups. If your car is anticipating upshifts, as it would be if you were on the accelerator pedal, it can theoretically shift 4 times in a second since it is pre-selecting the next higher gear once you request an upshift. However, dual clutch transmissions have this as the worst case scenario: On the accelerator, request an upshift, then immediately request a downshift...all while staying on the accelerator. When this happens, it has already preselected the next gear up, and it has to undo it and select the gear below. This can take some time.
