Care to elaborate? I'm considering switching to Cobb, but really like the versatility of the JB4 (on the fly map changes, fuel economy map, code reading and clearing, downpipe fix, data-logging, etc.). I'm sure there are a ton of threads on here about this topic, but I guess I'm asking for your personal opinion and why you choose Cobb. I put a lot of weight on testimonials - especially from people who've tracked their N54.
