The Akrapovic specific tune was custom tailored to the full evo system. Normally the bottom end power on the M3 suffers a little once you install the full Akrapovic exhaust. There is a dip in power in the low 1500-3500 range in the powerband. With the custom tune for the akrapovic exhaust you will see gains not only over stock, but over a standard ess NA tune as well. the entire RPM range has been optimized for the best performance.
