Are you sure it's NN6 and not MN6 which is the RPO for the ZF 6 speed transmission?

NN 6 *probably* means an emissions override for either a diesel engine *or* a car that's being exported.

It's certainly not for a diesel Corvette.

With gasoline engines NN6 probably meant leaded fuel compatibility along with some different calibration for use in countries that don't have emissions laws.
