Actually guys, the black box is true! All of our cars have it. It's a hidden "something" that records your boost lvls. When my N54 335i went in the dealer and didn't come out for 2 months, my SA kept asking me if I had any kind of a tune on the car. "luckily I really didn't" And before they declared my car to be a lemon, someone from out of state flew in and checked my blackbox. And the boost lvls were all stock. So they lemoned the car.

Now if I had a tune and they found out, I don't know what would have happened at that point....

BUT only in this extreme case they will check your black box. Not everyone can check it, someone from BMW corporate had to come and check it out. So if you have a tune, and nothing crazy bad happens like what happened to my car.....I think you'll be fine.
