Dinan Engine Software safely raises the rev-limit by 270 rpm, endowing your M5 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 improves throttle modulation in the sport mode.
