Dinan Performance Engine Software Kit for BMW 645Ci E63 2004-2005 (DIY)

Description:
 

Performance Engine Software is now available for the 645, extracting additional power as well as improving drivabiltiy. The software safely raises the rev-limiter by 250 rpm, enabling you to carry more road speed in each gear, as well as optimize shift points. The top speed governor has been removed, enabling the cars to reach their natural top speed. Revised EML tuning provides improved drivability by speeding up throttle response.

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. 

Special Note: 

K&N free flow air filter element recommended for optimum performance.
