It depends on the specific fuel really. Hopefully we will be tuning my 135i on race gas within the next few weeks. I believe there is a Sunoco station nearby that sells 100 octane unleaded at the pump. Since the car would be more resistant to knock we could tune it more aggressively via adjusting the boost and ignition timing in order to extract more power safely without fear of detonation. Once we do so I will make sure to share results and other information.

We may also be doing some testing soon with E85 on our shop 535i. E85 is pretty available near us and we've had great success on other platforms, but the fuel system on the N54 is a bit fickle so we will have to see how it goes.
