I have a JWT set up for Z32 maf and 550s on my SR. I understand that Jim Wolf writes conservative programs. When I went on a dyno the other day I saw that my AFRs were running rich, I wanna say 12s-13s (Im at work and I forgot my dyno sheet). Can I use a safc to lean it out a bit or should I go wideband? I know I can cut some fuel but would I have to mess with the timing, since i'm leaning it out a bit?

Any help would be great.

Thanks.
