How old is your cat? My car passed exactly on the money with the cat warmed up.. If I let the cat cool for 10-15 minutes before testing it would fail.. YOu mjight just need to borrow a fresher cat...
How is everything else with the motor running? How is the comopression and vacuum? When was the last time you did a tuneup?
If you were running it modified you may have burned up your cat already...

Re: (deadline)
Post a copy of your smog. Did you fail anything else? What mph did you fail your nox?
Timing can effect your nox, and your a/f too. If your lean nox will go up.
When I went to ref my car, I failed the 15 mph nox by a little. The inspector was col, and ran my car for a little bit to warm the car up more. It passed the second time he ran my car.
Edit: reading owns me. I reread the original post, its your hc that you failed. But try to post up numbers. Having the cat really hot should bring down the numbers down a little still
