Twin Turbo my BMW E60 M5
if i had a 2007 M5, i'd have it done professionally. So, having bought a 2007 M5, I think i'd afford to spend the coin on a professional setup made for my application.

the engine is already built for the most power that can be squeezed out of it. you add boost to it and its going to be a boat anchor. it will need to be torn down and compression will need to be lowered. i work at bmw. i know a guy that can handle the tuning part of it.
What do they use to tune that? a piggyback?
