1715 superchips and ethanol?
1998 expedition, 5.4. i just got the superchips programmer and used it and can already tell a difference even though i only have it on the 87 octane setting. my question is this, i live in south dakota and in order to get gas in a higher octane rating i have to get it with ethanol added into it. so does one keep it on 87 octane and regular gas or will it hurt or maybe help if i set it on the tow setting and used 89 or 91 octane that has 10% ethanol?
