This is a long shot as the thread is so old, but what settings did you have when doing your impressive 1/4 mile run?
Best 1/4 mile times?
I'm curious to see what the other e60 M5's moded or stock are running these days. My personal best is [email protected] 119mph. All I have is KN drop ins, charcoal filters removed, X-pipe and MagnaFlow exhaust. It dyno'd at 455hp uncorrected. 434hp corrected. 338 in torque. Most recent kill was a C6 corvette with exhaust, intake and tune.
