Hello,

Just got this tune done as I moved from a 93 octane area to a 91 octane state.

In any case it looks like it is knocking, but not near WOT. It looks to be pulling a lot of timing around the same cells. Is this expected? False knock or a noise artifact?

The car is an corvette LS3 2008.

Headers, intake and cam (.573/.578 230/236 degrees duration LSA 113)
