I would expect the same sort of upgrades for the m3 as they have for the m6 and m5.
I am still waiting for someone to develop a small turbine engine that can be installed in the trunk!
Capacity increase, mmmmm?? That must be really really expensive if it is the case!!!!!! Maybe its a turbo or S/C? Donīt see how an ECU can get you 25% increase in hp!!! Unless of course it is exaggerated!!!
