Default Atmospheric dumps affect tailpipe AFR readings ??
Just been pondering if this can be possibly true as a bunch of exhaust gases are getting dumped, and if so, which way does it affect the value, rich or lean??

Atmo dump does not affect the AF reading. Only a small portion of exhaust gas is being diverted, and fresh air isnt being introduced into the exhaust system. I true leak, such as a hole, can affect your AF readings.
