Looking into getting a wideband for my cobra, but i also have access to a five gas analizer/speed dyno. For a wideband to work correctly it has to be pre o2 sensor. I was woundring how come i can get a lambda reading out the tail pipe? Any light on this subject would be awsome. I understand the basics but would like to know more. thanks
lambda vs af?

You can put a wideband anywhere in your exhaust and you will get a reading. The most accurate is about 18" from your exhaust valves, and before any catalytic converters.
The tailpipe sniffers they use on the dyno do the same thing, but won't be as accurate since the exhaust has traveled through the whole system before reaching the sniffer.

Tailpipe sniffer reads richer or leaner?
Leaner,due to the air around it and possible exhaust leaks.

How much exactly? if you're not sure, just give me an estimate/guess? Would like to know. Thanks in advance.
Honestly,I don`t know,i`m going by what i`ve read.I`m sure it can vary.I`m sure someone else will chime in.

Why ppl these days seem to think negative instead of thinking positive. when someone is saying something good about someone, he sometimes roll his eyes?
Thanks a lot for the link Buddy. That sure helps.
