Once I strongly believed it was tune related for those tunes that cannot modify returned fuel mixtures while running higher boosts. I am not still not 100 convinced that it is not.

However I do believe fuel in general is the real culprit of the type oc octain and quality fueling the car.


I am nearing 12k miles on my 335is, no issues and I ride the hell out of this car.
