Running a little rich, should I cut fuel or add timing? I was seeing what people recommend for a car that is running with O2 values in the 0.925 range. I was thinking about taking out fuel till my O2's where about 0.900 and then adding in timing until I got KR and then back off the timing.
Would I make more power by staying richer, maybe in the 0.915 range and just use more timing until I get KR and then back off the timing?
Thanks!

Other than that, you have a great question. Do you add timing or cut fuel. I think you would need a dyno to complement your WB to answer that one.

You have to go with a wideband... I treid to tune from the stock O2's and ran in circles. Soooooooooo much easier with the wideband. Get the LC-1 it is cheap and easy to setup.
