I'm betting it's going to be a standard N54 single scroll, twin turbo, but with better cooling (larger center intercooler and maybe an additional engine bay one, plus an oil cooler), and a new special intake system like the one used on the X6M. Those changes in addition to the remapped software would likely net the ~345 hp that's been suggested. Right?
