I haven't read the whole thread yet- at work, but any mention of what that control box is in the footwell? Or is it just for them to tune a module down there?
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
