Meaning, that when your hellcat widebands are showing and command 11.35 Air fuel, you're actually at 12:1 or so at the tail pipe. It's an annoying part of tuning these things.
However, ever since the FlexFuel patch. Now at 0%, we're FA .068 which is 14.7. My question is, why is it that after applying the patch, FA goes from .0722 to .068?
