i have the cobb AP with a z4 35i DCT and it's a little strange in 1st 2nd and 3rd gear.

from 4th gear on it's fine and pulls like a freight train.
the torque is amazing - of course!

Unfortunately with the Cobb - I had to go from the most aggressive (20 psi) map to the middle (15 psi) map because it was causing strange behaviour in the DCT in terms of downshifting and unsmooth power delivery.
