How do i know my wideband is reading right? I have a afx ngk wideband http://www.bmotorsports.com/shop/pro...roducts_id/357
Well i went and got some dyno pulls and using the dyno jet wideband it was reading 1 afr off less than what my afx ngk wideband read on the street. It happen to me twice on two different cars.
What would be the cause?
