I have a 03 with edge juice with attitude and k&n intake. I purchased the truck without the edge. the milage didn't change when i installed the edge. I even run it on level 1 with my foot out of it. I have my fuel response set on 1 and all my defueling on. am I not seting it up right. any help would be appreciated. everybody I talk to personally gets better than my 15mpg.
