I got my 128i w/ ZMP up to 147 mph (GPS verified, well, at least crappy iPhone GPS speedo app verified) - car indicated a bit over 150/155-ish during ED. I ran out of road and didn't bother going out further to push it more, but it didn't seem like the 128i had too much more to give. Drank half a tank in just 30 minutes!
Anyone actually max out a 128i (N52) - not the speed limiter, but the true drag/engine max speed?
