Is that true? I mean the part about the 1M tune being the same as the z4 35is (and 335is I suppose)?
I always assumed it was but then read somewhere on here from someone that owned a 335is before and now 1M and he said there was a nice bump in power from one to the other. Possibly could have just been better gearing from the rear dif that was making if feel faster.
