FWIW the last B7 was more powerful than the last 760i by about 40hp. I can't imagine that the 760i would go TTV12. Just doesn't seem right for a BMW. I could see a blown V10, but that's about it.
Not too surprised about the HP numbers. It's a 25% gain over stock. Assuming they stuck with stock internals, upgraded the intercooler, and reprogrameed the DME, that's a pretty healthy gain.
