$3k for an ECU upgrade and A pulley, all together for a gain of about 40 hp!?! I think I would have a hard time walking after that. Just because it is a German engine they really like to stick it to people. Thats about as much as I spent on a complete turbo kit for a Mustang. I don't know why I complain though, I'll probably bite the bullet someday. Just think though if some company made reasonably priced performance parts for German cars, I would invest in there stock.

Unless a pulley made an additional 100hp I can't see it being worth $2k. IT DOESN'T EVEN HAVE ANY MOVING PARTS!!!
