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, which enables 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.
When ordering please ensure you have your VIN ready for the checkout process. It is crucial that it is typed in accurately and completely at that time.
While we offer the DIY kits in the stage 1 form, the additional stages will need to be purchased and installed at an authorized dealer as they require hard parts to function properly.
