well guys I just returned from my Beach trip. I ran the 87 perf tune the whole time. I got about 18 MPGs on the way down. I was cruzin' at about 70 MPH. I thought that was really good!!! On the way home I go about 16 MPGs goin about 75 to 80 MPH. My only problem that I ran into was, on the way home i noticed that when the torque converter would lock in, the truck shuddered like crazy. It did this for about 20 miles or so and then went away. Anyone have any idea of what that could have been?
