So for your 0-60 you kept in 2nd the whole time to avoid gear change and since you've got plenty of torque you're good to go. Makes sense. Now I don't understand why you're saying you can't do this with DCT? Couldn't you also set it to 2nd gear and gas it? Or isn't DCT so fast at shifting that 1st to 2nd will help?
It seems like the 335 offers the simplest and most flexibility for ridiculous increases in power with the JB4 and some simple add ons from BMW. I noticed the JB4 is also available for the 335is, seems like that should be better, no?
Yes and no. The DCT and 6AT are completely different transmissions with different capabilities and tolerances. If you put slicks and a tune on a 335is and try launching in 2nd gear with the DCT, it will break very soon. It is very fragile compared with the 6AT. You can start in 1st gear all day long, but because your numerically high gearing (in 1st gear) and high torque at low RPMs, launching effectively becomes problematic on the street.
I've driven a 335is and it was exactly the same as any n54 335i on 19" wheels. It looks good but the price is outrageous in my opinion for what you get.
You really want a fast 0-60 in all conditions (rain or shine)? Get an n54 335xi 6AT and tune it and get downpipes an intake and a water/meth system. You will be doing 3.2 to 3.5 second 0-60 times and quarter mile times of high 11's @ 118-120 mph.
