Two things the "performance" modules has over the stock. First is tighter tolerance and in some cases extended temperature components. This reduces the VRS "precession" or phase delay that occurs on reluctance sensors at high speeds when the amplitudes of the waveforms grows very large and the circuitry has to "clip" the signal in the input stages before the signal processing. This is a *GOOD* thing, and I would want one for this if for no other reason. The second advantage is the stability at the top end before the rev limiter cuts in. The perfornance modules have tighter tolerances on this circuitry, and so are more beleiveable in their stated "cutoff" points that the mass-made units that appeared out of the factory.
