It really seems to me like the JBx product is not that safe, and that its only thanks to BMW that it hasnt blown many engines. At this point, I'm leaning towards a Procede system, or Cobb. The information here was helpful.
I'm glad you could see through all the random comments, and come to the correct conclusion. I'm glad someone understands. That's why this is definitely worth the sticky
so people like yourself who are new and looking for a tune to go with can look at this and make their decision.
