To do the latter it take some rev building and "thought" by the ECU/TCU and those can result in some lag. This is NOT lag between paddle actuation and the beginning of the first clutching operation during upshifting, it is a totally separate issue.
The solution is simple - if you want to drag you need to use LC. Read my other posts on this. The system can not be much smarter or better than it is. It is up to the user. If you want to smoke the MT guy, us LC, if you can accept a launch lag just floor it. If you want to take of quick but at any pace slightly less than full LC just floor it a bit slower. The choices are abound. Learn your new technology and take advantage of it.

very well put...you guys have to realize that with dct your not using an automatic trans where you can just mash the pedal and the power is instantly there. you still have clutches...the clutches still need to engage and to determine how hard to engage depending on how you hit the pedal. the benefit of dct isnt from a dead stop...its after 1st gear.
