Not necessarily larger turbos, but tune for more responsiveness over the other N54s. I know the lighter flywheel will help, but the specs is exactly the same as the Z4iS so I can't actually see any difference between the two. They slapped a M badge on the engine, and I would like to know what they have done to make it different to the other iS.
I don't think it is right to call something M tuned if all they have done is put better cooling.
I know it is certainly a drive train improvement - it would be nice even to have something minor unique to this car.
It comes back down to are we willing to pay full M price for it. Typically you pay over 50% more for a M here in Aus, if it is like the UK at 30%, then it would be acceptable.
