Oh jeez man...you just took this all the wrong way....it would have been simpler for you to clarify your statement by saying that you meant that the inclusion of more boost as well as the de-stressing, better intake, and exhaust garner the extra +50ft/lbs.....simple isn't it?
BTW I agree with the majority of what you are saying and I do think BMW will probably be offering some type of increased performance kit in the future.
