My car is 2006 Base LS 2 with Lg headers and a Vararam CAI. It is throwing a code P0489. Reasearch points to EGR problem, but can't find anything specific on Corvette. Any ideas?

Since no one seems to have any ideas on this I searched for more info. On the GTO forums the info says the LS2 does not have an egr valve. Not available on amazon or ebay so it seems they are correct. Then what could cause the code ???

It could be caused by a dirty or damaged mass airflow sensor.

The GM shop manual does not list P0489 as a possible DTC for the 2006 C6. Maybe why no responses.

Check your gas cap to see if it's tight... common cause for this code.
