I'm assuming it's pinging. With our LS1s the cause (when using premium gas) is generally oil contamination of the mixture. Stop the oil consumption and you stop the pinging.
The most common cause of oil consumption is sucking it in through the PCV valve. The easiest fix is a 4 quarts of 10/30 and 2 quarts of 15/45 (or similar thick stuff).
This should stop oil consumption and if that's the reason for the pinging, it will also go away.
