As long as your Vette is all stock and well maintained, there won't be a problem.
If the plugs, wires, air filter, oil and o2 sensors haven't been changed in awhile, you might be in for a surprise. Good luck though.

it was 88k miles for that last test. The EGR valve itself got old and failed and it was actually a retest. The first time the HC's were even cleaner, but NOx went to a 1000 on one of the sections. easy fix, luckily.
still can't explain why your NOx standard is lower. My car has the YF5 Ca emissions option.
