Helpful Expert Reply:

With programmers like the Edge Evolution part # EP59YR you always have to make sure you are meeting the minimum fuel octane rating. Otherwise, you run a high risk of causing major internal damage to your engine due to detonation. If for some reason you can't access the fuel needed for the tune you are running, you need to switch to a tune with a lower octane requirement.
