93 octane tune?
I have the superchips 93 octane tune on my jeep right now but I noticed today when filling up that the highest octane here in Seattle is 92 with up to 10% ethanol. Is this going to harm my engine?
EDIT: Never mind. 91 is the highest tune and is installed. The website said 93 and had me worried.
