Dinan Stage 3 Performance Engine Software for BMW 545i E60 2004-2005

The software safely raises the rev-limiter by 250 rpm, which enables 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.

Stage 3 Performance Engine Software has been tuned specifically for use with Dinan's High Flow Intake and Throttle Body, optimizing power output as well as improving drivabiltiy. 

Special Note: 

For use with Dinan High Flow Intake System and or Throttle Body.
