Ive had the dopeys at my dealership refill my tank in the Z06 with 87 regular octane which obviously through the car into really bad misfiring. I put the same 108 octane boost and within only a few minutes of driving the problem went away. How much it is raising the octane I cannot prove but it WORKS.
