I noticed this as well. I run it in my X5 50i M-Sport and the V8TT loves it. It’s a animal and my draggy times have shown the fuel makes a difference.

Great question. Believe it or not, on a stock tune, octane makes a huge difference. The S55 has BorgWarner turbochargers and the latest (v3.06 - Sept 19) software that utilizes the octane in your tank to regulate boost pressure. I also made all of that up. I don't think it does anything if your octane levels are above 91.
