I agree with all the comments above except to say this. When the inevitable crowd gathers and you press that start button, the MMC Stage 1 doesn't disappoint.
I am very happy with the G56 system and standard ECU on my M3W. It's a big improvement over the standard system but probably very similar to the Morgan Stage 1 in performance if not noise. It doesn't disappoint on start up either, a nice deep rumble. The insurance (G&W) is unchanged.
