Hoping someone can help out. How is AF determined after warmup? Is it just from the Fueling Table? The problem I'm having is that after installing the SC (same MAF same injectors) my A/F is richer than it was N/A. Also, turning on the A/C on sends the A/F richer too. According to my Fueling Table A/F should always be 1 below .40 load. I'm thinking something else is modifying the A/F, but I don't know what.
