I'm an independent observer here, who is trying to decide what tune to buy come spring. I'm certainly no expert in tuning, but as an engineer I like to try and undertand the details and all the options. I understand the issues on timing control, and can see why you need it. 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.
