If you get a wideband O2 you can tune it on the street, just retard your timing to a safe level than tune your A/F until you get that right. Once you have a safe A/F you can begin advancing the timing and adjusting A/F accordingly until you reach a good level

try cybernation ft lauderdale, mic turbo, matrix, murrays, if they dont have they will lead you to one, I'm very sure cybernation have one.
