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, which enables 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.
*Dyno results when combined with K&N free flow air filters (available at additional cost).
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.
This kit may not be compatible with your vehicle as BMW employed multiple connection methods during the year range in question. Before purchase please consult the installation instructions linked above to verify a K-LINE connection method is valid for your vehicle. If a round under hood connector is present this kit will NOT work for the vehicle.
