Ok so I think I about have it tuned right except when I have WOT from high 3rd and into 4th, my O2 reading starts diving from 750 to 590 and then it goes straight to like 034 or some super small number. My knock retard goes from .5 to 1.5 only between shifts so I think that's OK. I pushing around 24psi to 26 psi. I don't have a wide band O2 sensor, does this have anything to with it? Thanks!
