Here's the word from 3zero3:
The bottom line is they can do it and they have great faith in their technician's abilities, despite the fact that they actually have NEVER flashed this tune on to any E90/91/92/93 car before. They want $420 to "pull the TCU, flash it with WinFKP, reinstall and verify performance of the tune".
I'm going to look into getting the cable for this since I want to do some other coding functions. Appreciate you looking into this Thaar. Let me know how it pans out with the other guy.
