I just loaded the BM3 on my N63TU2 Engine(almost the same with a few updates as yours for 2019 model year). I can't tell you the exact output increase... With stage 1 93 octane map it does have a bit more oomph especially in sport mode, but it wasn't mind blowing like i expected. I will probably need to get some catless downpipes and up it to a stage 2 map, which I expect will at least give me a more aggressive engine growl and a slight boost to hp and torque. It was pretty impressive stock in sport plus, so maybe my expectations were just off. I still love it, but on its own i am not sure I would do it again. Maybe the stage 2 will change my mind.
