I have a 2008 C6 Corvette W/auto. 416CI ls3, 3800rpm stall, 102 intake, full exhaust, injectors, etc.
The car has a len spike at cruise and I just cant find what is causing it. I have checked all my ground wires and attached another ground from the battery to the engine block. Under acceleration the car is perfect. I have attached a scan and the tune.
