Engine problem
2005 Chevy Silverado V8 Two Wheel Drive Automatic 50,000 miles

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.

The problem is from all of the performance modifications to the powertrain. You might have to go to your local race track to purchase high octane fuel to try.
