This is why calling any SC as not working at low rpms is pretty much a fallacy. If you look at the torque curves of any of the common SC kits out there for the M3 all offer a significant boost across the entire rpm range. Again, yes there are differences, but they are not enormous.
very helpful.... thx
so in the real world the useable power will be much the same for all these kits?
