tailpipe.  When I told them that we all run cats, they said the A/F
results won't be correct but they will be able to tell if we are rich or
lean (but not the exact ratio, I guess).

Question: For those that have done dyno days, can the OE sniffer tube
just downstream of the turbo be used to get the correct A/F ratio OR do
we really need a second "bung" downstream of the O2 sensor? I hope the
sniffer tube can be used because all but one of the seven of us signed
up are running OE down pipes (the seventh has a Gen IV Stromung) and the

likelihood of us all running out and getting a bung installed before
March 11th is slim.

Thanks in advance.
