I gave my car another run yesterday at Willowbank Raceway with the only change being the addition of a bottle of Nulon Pro Strength Octane Booster. Ambient temperature was 12C higher than before and the track condition wasn't as good. I managed a couple of 11.5s runs similar to before but to my surprise next to no timing corrections. Even when I ran 100% E85 before, the engine has always had heaps of timing corrections so why the change now. Does this mean the previous timing corrections are false?

E mixes create gum over time. Also United E85 can be iffy from time to time. I run fuel doctor to keep the gum you will get from E blending out of the system. Possibly the octane boosters cleaning elements helped?
