Truck is sitting right. Now a few minor adjustments to the trailer.

How the hell do you all get such good mileage.....I have mine tuned with BB and still only get maybe 16-17 highway. 18 if I'm babying it. City I average 14.

Will tuning out the afm really help that much? Or do I really need to replace some of the internals to really get it more efficient.
I really don't know honestly. I filled up 1 mile from my house and jumped right on the interstate. Set the cruise on 74/75 and didn't take it off unless I had to. 5 1/2 hour trip. When we got to the city I checked it and it said 21.8 average. Should have took a pic

Must've been flat land. I got way better mileage in FL on vacation. Up here, no way.

Up here to the right
Tuesday i filled the truck up and we (wife and 3 kids with a smaller cooler and few bags so not too much weight), jumped on NYS thruway north for 2.5 hrs to an amusement park, 6hrs there and then 2.5 hrs home with cruise set at 70-73 (troopers every few miles it seemed like) the whole trip there and back and best was 17.8....IMG_4784.JPG
It went to 17.8 right before we got off the thruway...:emotions122:

It would be interesting to know what rear end you guys have in your trucks. Mine has a 3:73 so obviously highway mileage suffers at higher speeds.
