Dinan Performance Engine Software for BMW M5 E39 2000-2003

Product Description
The software also removes the top speed governor, enabling the cars to attain their ”natural” top speed. The software also speeds up throttle response in the ”standard” mode and improves throttle modulation in the ”sport” mode.

Dinan Engine Software safely raises the rev-limit by 270 rpm, endowing your M5 with a broader power band and greater road speed in each gear. 

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