i just returned from a 300 mile trip from south texas to north louisiana and i got an amazing 14 mpgs. the most ive ever gotten on the highway was 12.5 and lately ive been getting 11 highway. i bet it helped that i had a pretty strong tailwind helping me out lmao. the funny thing is i havent done anything to the truck that would affect milage except for putting on my headers, but i didnt think that running open headers would bump my mileage that much. i figured it would hurt my mileage more than anything.

 

Tailwind, less restriction, I presume cruise control, and smooth driving over that distance....makes perfect sense you'd get that high. Well done!!!

 

not to bad i get aabout 13.5ish with my truck it has stock exhaust beside for a flowmaster muffler and gutted cat but thats nice mpg you got there buddy

 

Thanks, and o yea i dont have cruise control, and i was doing 80 most of the trip

 

Slow it down to 65 if you want more MPG. Whenever I'm driving long distance through Iowa I get 16 to 18, provided no head win.

 

Lol i normally drive like a grandpa but i was following my sister and she drives like a bat out of hell,

 

hey backwoods. on you sig it says you have a hybird t case whats up with that?

 

i built it out of parts from a nv231j(from a wrangler iirc), a np321d(my orignal before it exploded), and a np231hd, along with a few weld beads in places these things are prone to cracking. and when i have money to have a new driveshaft built im gonna install a SYE(slip yoke eliminator)
