Just wondering if this is worth trying out? Not too worried about the gas price difference, just wondering if there's any gain between the 87 and 91 tune like they advertise. Could it hurt the Jeep at all running 91 octane? I'm assuming superchips did their research and wouldn't have the tune available if it would damage the vehicle, but I guess it never hurts to ask anyone with first hand experience. Thanks in advance.
