Wow, BMW has really made this thing mission impossible to tune. Can't wait to finally see some tuned M5's in the U.S, 590 Tq!! Can't wait see some dyno tests and some real world results from this tune.
Im a little confused though, tests are already showing its over the 600hp mark. So could this tune mean it could be over 680-700hp?I Wonder what kind of power to the wheels a car with this tune will be pushing.
Time will tell I guess.
