The only thing the OBD testing checks is that there are no fault codes on the engine and/or emissions equipment.
Here's what it says on the NYS DMV Site:
"This test examines the Malfunction Indicator Lamp (MIL), also known as the "check engine" light, for operation/illumination, and verifies the test results of the vehicle's "on-board emissions diagnostic" system."
So the delete will shut off the MIL, but not sure if they can tell from the re-program that the EGR is no longer connected.
The delete doesn't just shut off the light like some old chips or modules did at every start up. The tuner will actually go into the ECM perimeters and programs the EGR and other devices out of the truck as if they never existed.
I am not sure how thorough the stations are in NY, but most here in Texas don't even have the necessary hardware/software to be able to tell if the truck has been reprogrammed or not. Most only have an OBD fault reader and that is it. The main concern where I am at are safety violations, not emissions violations. Especially since the population is not dense enough for NOx to cause any harm.
Here in the Houston area (largest city in Texas) and probably the highest concentration of trucks, my diesel truck only gets a annual Safety Inspection to the tune of ~$13.
