like theres the 3 series 4 door category to choose from, but then they dont let you choose between the 328 and the 335.
if you wanna do it go ahead, but it looks like a scam that could kill your engine and will definitely void your warranty

Conversely, it is so fake, that I doubt it does anything at all so it seems unlikely it would damage your engine!
The fine print says that when you turn the chip part way is when it gives more horsepower and better mpg. It implies that it is doing this at the expense of poorer emissions. I suppose BMW might be able to improve mpg of the engine if it didn't have to worry about the emissions. Of course, if it hurts emissions then it should be illegal.
