D900-27Z-KIT

Dinan Performance Engine Software Kit for BMW Z4 2.5i E85 2003-2006 (DIY)

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

Software Description:

Dinan Engine Software safely raises the rev-limit by 240 rpm, endowing your car with a broader power band and greater road speed in each gear. The software also removes the top speed governor, enabling the cars to attain their ''natural'' top speed. Reprogramming of the drive by wire throttle system speeds up throttle response, dramatically reducing the delayed response to throttle inputs exhibited with the stock programming.

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

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.
