I don't think stickshifter69 is saying there is anything wrong with the Cobb per say, rather that on an owned vehicle you want to more catious, and Dinan comes with a full drivetrain warranty while Cobb does not (I think it's for the remainder of your BMW warranty, or 2 years if you are not under warranty). The warranty is a major part of the premium on Dinan, but for best bang/gain for your buck, Cobb is the way to go (but if issues come up… you're covering your own)
