Dinan Engine Software safely raises the rev-limit by 150 rpm, endowing your M3 with a broader power band and greater road speed in each gear. The software also removes the top speed governor, enabling the cars to attain their ''natural'' top speed. The software also speeds up throttle response in the ''standard'' mode and provides for more controlled throttle modulation in the ''sport'' mode.
