Dinan Performance Engine Software for BMW X5 4.4i E53 2005-2006


Performance Engine Software extracts additional power as well as improving drivabiltiy. The software safely raises the rev-limiter by 100 rpm, enabling you to carry more road speed in each gear, as well as optimize shift points.

The top speed governor has been removed, which enables the cars to reach their natural top speed. Revised EML tuning provides improved drivability by speeding up throttle response.

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

Special Note: 

Only for 2004 - 2006 models. K&N free flow air filter element recommended for optimum performance.
