Slow o2 crazy afr

[wadesns]

I recently went form Auto ve to running SD and have noticed that my afr's are no where close to what they should be. While running auto ve they have been within +/-.2 but now that i have changed over they are +/- 1.5 I am not sure what could be causing this but have noticed that my O2's are really lavy. hey are new about 100 miles ago but don't change at a very good rate. What table needs to be edited to make them switch faster and what else could be making my afr's off so far.

Thanks.
