The reason I ask is because if it's running this rich it might not be a complete burn of the fuel. So residual fuel would be accumulating to a point.
I cant find mine, but I have one where an intake/catback cobra (stock tune) goes from ~12 @ 4500 rpm and dips down to 10.8 @ 5000 and ends at ~11.2 @6500 rpm.
