What I can say about it, it is not the most aggressive tune out there, but it is the easiest and best engineered.

A 9% max potential HP gain (49 hp) on the M50i does not seem like much. I wonder if the wife would even notice it. Do they give refunds if you aren’t satisfied? Dinan has a 40 HP boost kit for the 40i with a base of 335 HP.
