what are safe/normal A/F ratios for our 1uz-fe's (non boosted AND boosted)?

at:

idle
cruise
wide open throttle

thanks for any all help!

where would you put the wideband sensor? since it's a v8 would i need to buy 2 wideband sensors and place them close as possible to the headers?

just curious if i placed the wideband sensor further back where the two pipes merged, if it would have MUCH variance (vs. placement near headers)?
