Are you blending it by yourself (with say 25% E85 and 75% 91/93 premium pump fuel) or are you buying it at a station that sells it from the pump? I suspect that the 'pump' E30 is blended with 87 fuel so it's effective octane level / knock resistance is lower than what you'd get if you blended it yourself?
