Does anyone out there have the Edge EZ on an 04 SO? I have an 04 four wheel drive quad cab with a 48re transmission. The truck is stock. I am wondering what to expect for a difference in power and fuel mileage. I tow a 3k boat and trailer every weekend about 200 miles round trip. I average about 16mpg on the overhead. Would it be possible that my mileage might improve with the EZ? Any information would be helpful. Thanks.
