NE1 Emissions
Based on my searches of this forum, it appears there are no mechanical differences in tuning or emissions equipment on 2013 NE1 (Northeast) emissions certified vehicles.
If anyone has information to the contrary I would be interested in knowing for the purpose of comparing vehicles under consideration for purchase. All that is required in my state is FE9, Federal emissions. I don't want to purchase a vehicle that is detuned with regard to timing or fueling or that has additional emissions equipment.

No, there are no tuning differences. All C6's are built the same. The only difference is the sticker that goes on the finished car designating Federal, Calif or Northeast certification.
Here's an older post with a basic description:
Here's an older post with a basic description:
As noted, all Corvettes are mechanically the same and meet 50 state federal emissions from the factory. However, that is not good enough for a new car registration in California. It must be ordered to meet California emissions and reflect that on the RPO codes. While it is ridiculous and simply bureaucratic red tape, it is what it is.
If your car does not have YF5 you will have a long, up hill battle to register a new car in California. If it is a used car and has more than 7,500 miles on it, it can be registered but will have to pass a smog check.
Emission Ordering Options:
FE9 FEDERAL EMISSIONS. Use for ordering vehicles that will be registered in all states except California, Connecticut, Massachusetts, Maine, New York, Pennsylvania, Rhode Island and Vermont.
YF5 CALIFORNIA EMISSIONS. Use for ordering vehicles that will be registered in California.
NE1 CT/MA/ME/NY/PA/RI/VT EMISSIONS. Use for ordering vehicles that will be registered in Connecticut, Massachusetts, Maine, New York, Pennsylvania, Rhode Island or Vermont.
The decal that people are referring to in the above posts looks like the one pictured below. This is a NE1 decal used for cars to be registered in the New England states. Notice that it specifically states California compliance on it as the New England states have adopted California emissions.
