Dinan Performance Engine Software Kit for BMW 550i 650i 750i and 750Li (DIY)

Dinan D900-505-KIT

All orders will include an AutoTalent window decal
Description:
 

The software safely raises the rev-limiter by 200 rpm for manual and SMG transmissions and 100 rpm for automatics, 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. 

*Dyno results when combined with a K&N free flow air filter (available at additional cost).

Special Note: 

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