dude, your car is running AWESOME for those kinds of HC/CO numbers. perhaps a tiny bit rich as the CO2 is a little low unless thats how the V8 likes it (i did smog the other day and was at 14.8/14.9). looks like your cat may be getting long in the tooth though. why did they put test weight at 4000? mine is 3125, which is still 400lb more than the car actually weighs

Ya, I'm not sure on the weight. The weighing they did showed that the rear of my car was 1464lbs and their computer had an error saying that it was too light. After the second weigh, which showed the same number it just tested. I think they may HAVE to test it at a higher weight because of the motor. I think that is the test weight of a Camaro/Firbird/Corvette.
What does the CO2 number signify? The last time I smogged the 3.0l that was in this car 2 years ago that number was into the 15's.
The higher than normal NOX numbers are because of the lack of EGR function. It's there, and on in the computer, but EGR only functions on an LT at greater than 14% tps. At 14% tps your flying, just for reference I've never exceeded 8% tps in normal driving. All the EGR scavaging is done by the cam overlap. I should also say that the tune in the motor will allow for up to 48* advance. Usually it hovers at 43-45 while driving and at idle is at 18*. It's technically not adjustable (technically).

CO2 is your efficiency indicator. Ok to have high number there as far as I know.
Must be a hassle having to deal with emissions/smog. 95 and below don't need testing here in IL but your supposed to have the same emmision controls as the vehicle came with factory, but they don't check. I also have to learn about all the smog regulations in Cali at school even though I live in IL! Might head to Cali for some Nissan training though.
