finally got the rig on the highway and got to do better than 65-70 mph for a sustained period of time today. prior to the mods i have listed in my sig the truck was bone stock rolling 275/55r 20s. still on the same tires and with the mods i went from 19-20 mpg to 26.2mpg as read on the cpu. i have not hand calc'ed it yet, but thats some nice cpu increase.

 

Hmm.. nice work so far.

 

DID YOU GET OVER 700 MILES ON A TANK ?
MY BEST IS 655 MILES ON 33.6 GALLONS
OR 19.49MPG (4.10S IN THE REAR AXLE)

 

only did a hundred fiftyseven miles. it was late when i got back so i didn't get to fill up and hand calc the mileage.
