I failed NOx in NJ by 800. It was determined my cats could be bad (EGR was tested and they said it was fine, but now I get codes from the EGR a few months later...go figure). I retarded the timing A LOT. The car felt like slower than a V6, but I passed NOx and that was the only thing I did. I am not sure of the exact timing I had, but I went from 15 to below 9.
