How much does the 4.4 twin-turbo take?
It is a twin-turbo V8 with substantial headroom, even from a high factory output. Stage 1 works with standard hardware.
Does it affect the xDrive system?
No. The work is done on the engine ECU and does not alter the operation of the all-wheel-drive system.
Is pop and bang legal?
It is not permitted for road use in Spain: it alters the exhaust's approved behaviour. It exists for track and closed-circuit applications.
