Rod your O2 needs back pressure to work. I don't believe in using an O2 gauge to dial your car but it can save your engine if your going lean at high rpm. Do your testing with a long extension or a muffler and get your reading. Then run your extensions with a paint stripe and cut at the end of the paint burn. 'OLD SCHOOL'
