Ok, bought my car 100% stock from a BMW dealer; and I did all the work as previously stated; There is no tune on my car. Like I said, it works for me and I am sure I am not the only one, just offering a cheaper solution for others. Again it's a "mechanical" fix, there's no reason it shouldn't and I'm sharing first hand info..
