I started logging and I'm running rich. In fact , I can smell it and my exhaust tip is black.

What are some ways I can lean this thing out. I don't have a wideband.

I started by going to the O2 bank tables. Less mv's to lean out correct? I heard trying to obtain the correct A/F by your banks isn't a good idea, but I'm running extremely rich. Any ideas on how to lean me out some? What about the flowrate vs. KPA table?

I dont seem to have any kr and I'm running 20 degrees of timing.
