Hi All,
I'm doing some tuning before the winter comes and I'm trying to get a handle on ideal AFRs. Since the temperature has dropped I'm experiencing some popping and hesitation when I go hard on the gas under 3K RPM, I've done a RAFIG + Calc VET. Her are some images of my AFRs, does this look normal?
