I do see a potential for tuning for higher octane race gas based on the current boost and injectors, this would allow for more advance timing which should be able to generate more power, but I don't think many of us are willing spend the extra money to dump high oct race gas in our SUVs unless we are drag racing someone

theaudir8fan fan is right. Not enough demand for our vehicles for the big companies like Bosch to invest in R&D.
You are almost at the limit of possible bolt on upgrades for your X6M. If you are looking to go faster, you are probably better off buying an M3, M5 or M6 since they have much more performance parts available.
After finding out the availability of performance parts in our vehicles, I'm probably going to stop spending $$$ on my X6 after AR DPs and start looking into M6 - V10. I love that F1 exhaust scream.
Good luck!
