Dude you have an exhaust leak some where.
The only thing that would cause NOX numbers that high is that air is getting in before the cat. This causes the CAT to burn ultra-efficient and raises the temp of the air high enough to cause NOx.
I bet your Co2 and other hydrocarbon numbers are really really low.
Double check your header gasket, and your gasket between your header and your cat.
