Dinan Performance Engine Software Kit for BMW X5 4.4i E53 2000-2003 (DIY)

Special Note: For 2000 - 2003 models only. 

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.

Software Description:

Dinan Performance Engine Software unleashes more power by re-programming the fuel mixture and ignition timing parameters of the engine management system. Furthermore the software safely raises the rev-limit, giving your BMW a broader power band and greater road speed potential in each gear. Significant gains are also achieved at part throttle, making extra power available where you spend the bulk of the time driving. The top speed governor has also been eliminated, enabling the vehicle to achieve it's ''natural'' top speed.

Note: 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.
