Call BMW and talk to the nice technician and ask him what HP at the wheels was, he will tell you. That’s how I can up with the math. Are you not familiar with this. 456HP x 85%= 387HP. Dyno reads 545HP which is 159HP over stock wheel horse power. So if I or a dealership sold it it whoual be a 2019 BMW “” “” tunes with 609HP!

I vaunt do videos?
