So why wouldn't BMW install it to begin with? Someone in a garage in Simi Valley is so much smarter than everyone in Munich, that BMW just can't figure out how to duplicate the effect?
Please help me understand this. I want to believe...so much...that I can add 10 horsepower for $280 without any negative effects...but I can't. Both physics and economics scream out: "Highly unlikely."
Anyone else having a trial of faith?

This entire stupid rant could've been completely avoided had you done more reading. Besides, if you're freaking out about a piggyback that actually changes AFR values claiming to increase power, I can't imagine how you feel every time you see a K&N air filter claiming to add 14 horsepower.
Good luck to you.
