Dinan Performance Engine Software for BMW 545i E60 2004-2005

Dinan D900-455

All orders will include an AutoTalent window decal

Performance Engine Software extracts additional power as well as improves drivability. 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.

*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.
