Bm3 Stage 1//F30 328i N20 xDrive//Launch Control//

2015 BMW 328i xDrive w/ Bm3 Stage 1 93 Octane I was hesitant buying it at first due to the price, and potential harm it would do to my engine. I did some research and honestly came to the conclusion that this is a smart buy, it has made the driving experience so much more enjoyable, and has just been perfect. (I recommend getting a cat less down pipe, and a muffler delete, it will only make it that much better for such little cost.)
