Message Race gas all by itself burns slightly richer than pump gas. At idle my car has a worse lean miss with pump gas than race gas. The target program for o2 sensors is not perfect so unless I take the car to JWT to fine tune, the idle will never be perdect. But yes, race gas makes the mixture slightly richer which is noticeable on my car anyway.
