I know that manual boost controllers don't apply to our cars, but I don't see what is so funny about the first link?
Why shouldn't you be allowed to sell a MBC? I don't get it. Manual boost controllers are almost always better at holding boost solid and making a better boost curve then EBC's that are usually a pain to set up and fluctuate much more. I don't see how it is a piece of crap, even if it is a no name brand.
Edit... ok, I just saw that the auction title said it was for an e90/92.
