    What is a dual tune?

    I'm getting a cobra that is currently tuned for E85 only. However, the owner says it can be "Dual Tuned" for regular gas. If it's dual tuned does it mean that it can still run on E85 until the tank empties and then I can switch back and forth from E85 to regular gasoline as long as I don't mix...
