The other option (and probably the better one, tuning-wise), would be a standalone DME/ECU, but this is a long-shot for most street cars as you'd have to compromise on most non-essential items to make it work. This is OK for a race car, but a serious deal-breaker for most of us.
There are several other hurdles as well, but I digress.

Motec M1 can do it, and you def won't sacrifice too much as it has full CANBUS integration. Now for Flexray I'm not sure, not sure if the S55 DME has flexray. The problem is getting someone to write the custom firmware.
There's a guy up in Oregon that can do it, he's done plenty of street & race cars with full custom M1 firmware.. question is... who's going to be the one to offer their F80 up with a turbo kit.
