We can do it. I'm assuming Mark is going to reflash your ECU after we update it, as you'd lose his performance software in the process. Give us a call when you want to move ahead with it.

what's in the update?
Mark D has some tune that will only work with updated software on the my e39 m5. There were some software updates from dealer since 2000,
