Although I'm surprised S3 on the N55 "only" gets you to the 380 hp / 400 tq mark -- doesn't it get you ~440/440 on your N54 E92 now?
Good luck on selling the E92. I hope you can find a fellow enthusiast to take it and appreciate it for what it is rather than having to sell it to a dealer where it will go who knows where. My car is running particularly well in this cold weather too -- even more so a month ago when it was in the 30s. But it's a cruel irony of nature that temperature drops increase engine power but also reduce available traction.
Actually, the F30 has a different DME, which is one of the primary reasons that the previous N55 software upgrades won't work. There are some milder tunes available right now, but they're mostly just boost-increasers. Probably going to take some time until they get it all decoded and such.
My current S3 software plus the exhaust, intake, intercooler, and oil cooler give me around 410/440 (flywheel); the N55 S3 gets you something around 380 at best. Word is that the N55 is more about efficiency than pure power, which is why the N54 is still being produced for the "IS" models, which continue as E92 and E93 cars. I'm going to stay conservative on the F30, and enjoy the dynamic handling and added space/doors. I can always get my 6-speed fix in the 128 convertible.
