Dinan Performance Engine Software Kit for BMW M5 E60 M6 E63 M6 E64 (DIY)

Dinan D900-51M-KIT

All orders will include an AutoTalent window decal


Dinan Engine Software raises the factory rev-limiter by 150 rpm (8400 rpm maximum), endowing the V-10 with a broader power band and greater road speed potential in each gear. The software also removes the top speed governor, enabling the cars to attain their ''natural'' top speed; and the V-10s WILL pull right to red-line in top gear! The software also speeds up throttle response, providing a sportier feel and improved modulation capabilities.

The combination of Dinan's re-calibration of ignition timing and air/fuel ratios, along with a simple modification to the stock air filter elements, produces a maximum gain of 5 hp @ 8100 rpm and 5 lb-ft torque @ just 3000 rpm. Dinan's software also provides re-calibration of the factory ''torque limiting'' programming, ensuring that maximum power is available under varying driving conditions.


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.
