You are not going to get much benefit with the supercharger until you get the rpm up above 6000 rpm.
Here is an estimated crank hp plot going through the gear and final ratios of a DCT with the stock motor and the 535 while accelerating.
As you can see, the difference comes into play as the rpm's increase.
Right after shifting into 2 gear ( 45 mph and ~ 5000 rpm) there is little different again until the rpm's increase further...
