Seems like I have quite a bit of homework to do this weekend! LOL

@AJ/FormS I'm going to copy what you said and make it into a guide that I can follow. It seems to me that you're trying to say that I shouldn't worry too much what that gauge tell me and go by what my engine likes.

Amen.
Below the vacuum peak, and most especially from idle to about 1200 with a mild street cam, there is so much BS going on in the intake that the AFR gauge can flat out lie. A wide band can help you set up for power, and the regular type can help for everything else .
I try to set up my car to cruise at a higher rpm than the vacuum peak in neutral. Then the AFR tells the truth and is a great way to set up the cruise for lean running great mpgs. But below that I pretty much scream liar at it. You can only do so much with a carb
