good to know you like the 4.10 for the 6sp. so you noticed a big difference in acceleration?? also is the cruising really not that much higher on the rpm??

The 6MT and the DCT have entirely different gear ratios, with the DCT being much lower in the first two gears, in particular. Some people say that the 3.62 is too low for the DCT, but that depends on how you plan to use it. (It'll work and feel faster, but is actually slower in the 1/4-mile). Anyway, if the 3.62 is marginally or arguably too low for the DCT, then the 4.10 is going to be way too low, such that 1st gear wouldn't even be needed to get rolling. Also, that would likely confuse the DCT's computer no end.

So, the 4.10 is superb for the 6Mt. I've got it and love it. If you want to change the FD on a DCT you should search the threads about that to help you decide which you'll like most. There's been lots of discussion here.
