Good point, although that gets put back to those asking the question he quotes. There are some who want the technical differences and some who just want the highest power output #. This thread itself is great, although should be done by someone with less bias (although you make a good point of having first hand experience, your experience would not be as valued due to your previous employment in the majority of the worlds point of view) and not leaving out other companies who have kits on the market. There's so many S/C E9X M3s out there that I bet this forum only accounts for 1/3 of them so who can say who has the most sold, or on the track solely etc. Keep in mind how many BMW forums there are.
Back on topic do you have dates of the dynos?
To make it clear I am not taking sides...but the informative thread doesn't seem transparently informative.
