I don't put as much faith in trap times anymore. I run 12.7@ 110 with 306whp (my trap says I should be close to 350whp).
That's the thing about the N54, they need meth or major cooling upgrades if they're pushing more than about 380bhp. There's a reason Dinan will deny warranty coverage on their stage 3 tune which only brings you from about 350bhp to 398bhp.
The N54 is a capable motor, but so was the LT1 once you worked out the problems. From what I've seen it has major cooling and fuel issues that have to be rectified, and even then you need to upgrade the turbos if you plan on pushing more than 400whp, unless you want to run meth everywhere you go.
All in all the fastest no nitrous time for the 135i was set by ACR running 11.5@125. That's nothing to scoff at, but that was a motor where the only thing left stock was the bottom-end and it was on meth. You can achieve 11.5 in the SRT6 with far less.
One last thing, the 6-speed vs the auto, that's what the AMG Speedshift upgrade is for
