I have 11 to 1 on one of my builds. I dont have knock just a slight ping under heavy load. But normally happens when the bike is hot from light to light traffic .on hot days . . Doenst happen under normal operating temps.
Big reason I brought up IAT spark correction table. It is the perfect place to retard some timing because of light to light or stop and go traffic.

I don't know what tuned for track means. I tune for best power, street manners and best cruise MPH on every build all at the same time. Different parts of the calibration will allow for this. You don't cruise at 100kpa and you don't worry about fuel mileage if you are always in the 100kpa column. That is why the ECM wants kpa, rpm and throttle position.
