Not true. I am running the Stage 2 in my 535i xDrive right now. The Burger Tunes for the 535 just does not have all the interface options yet through the steering wheel.

The BMS stage 1 tune is the only option that currently works on the N55 535i/xi models. From what I know, the stage 2 is not officially released for the N55 535i/xi models and is currently in testing. I'm sure that it will be officially released soon.
