when i accelerate i can more pings in my motor. I have tried octane boost. did not work. the motor should be running off 97 octane. they only sell 92 in Oregon with 10% ethanol. It is a factory Corvette LS1 block with vortech heads. it has a hyertech power programmer 3, throttle body spacer, K&N cold air intake. all of this came from the dealership in Arizona installed. I have moved to oregon and now my truck is running bad.
