Poor C6
until then, i believe your car has a tornado, a whistle in the exhaust to sound like a supercharger. the vettes you beat were trying to pull into a parking spot at the grocery store, you were backing out, and counted your "bus lengths" as they grabbed their shopping cart and you drove away.
on a side note, it does look and sound great. props, cant wait to see it in action.
Ohio, one more thing to consider at 680-700 whp is a secondary fuel system. Stock fuel pumps can overheat under heavy work, If your tuner suggests it, I'd strongly consider.
