Dinan Performance Engine Software for BMW 550i 650i 750i and 750Li

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

Performance Engine Software extracts additional power as well as improving drivabiltiy. 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. 

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