Well, tthe numbers are certainly odd. I have no explanation for the drastic increase in NOx, except for possible error on the part of the inspector or analyzer.
So, I have 2 suggestions.
1. Clean the EGR, test for function, clean the exhaust gas tube that goes to it.
2. ask the manager, or call the company office, ask to speak to the QA technical person, or call the Texas Dept of Public Safety 1-800-396-9394 ask for Santos Olivarez, which I believe oversees the emission testing, ask them when the calibrations for the analyzers are done, then try to test as soon as possible after the cals are done.

Good Luck, and thank you for your help to clean the air.
