Ok, I passed the AZ emissions but my NOX was just on the verge of failing.

My results are:

HC grams / mile 0.76 , 1.60(baseline)
CO grams / mile 3.67 , 15.00(baseline)
NOX grams / mile 2.40 , 2.50(baseline)

Even though I passed I would like to get my NOX reading down since it seems close to the max. After searching it seems to be EGR or cat related but I'm at a lose with emissions. Are those results even anything I should be worried with or is it ok? I want to do my part to keep the AZ air -clean- ha.
