If you have the bung welded to close to the end of the tail pipe you will have air sucked back in tail pipe @ idle and get all kind of false readings. I have a NGK wide band o2 sensor and meter and in thier directions they say to install the bung 10 dia. of the size of the exhaust from the end ie." 3" exhaust =30 in." from end. Most folks say to mount it at about 6" from exhaust outlet of the turbo. I don't know what is best but mine works fine. I have 14.50-14.80 on idle. and with it set at about that it elimated the lean popping on deacceleration. Good luck
