To be honest, I'm hesitating myself between that and a JB3/JB4. I like Hartge's reputation a lot, they have over 30 years of experience in motorsport and tuning BMWs. They are kind of like Alpina and AC Schnitzer, although I guess those two are not very famous neither in North America.

That been said, I do not know more about the tune than what I posted. The fact that it connects to 7 sensors (and that they are German ) does give me confidence that they have a well engineered product, but I'm still looking for more information.
