Just for shits and grins I dropped in behind a big rig on the highway yesterday and reset the dic.... leveled out around 17.8 running 70mph. I've only got about 2800 miles on the truck, and so far thats the best the dic has ever displayed.
going to roswell and albuquerque from dallas and back this weekend, will let you know. so far around town I have only run 10 gallons thru it @ 16.7 mpg. got to visit the wife's folks then go get my 51' chevy pu. I used to have a 327 64 vette motor in it but now I will be putting in a bbc unless I can find a wrecked duramax, that should be interresting to wire

I have a 3500 2008 Crew cab Dually with 7,000 miles. I am getting around 9 MPG towing a 10,000 lbs trailer. Empty in town I am getting about 12 mpg and empty on the road around 15 MPG.
I installed a Hypertech chip and a Banks intake system. After 3 tanks of gas, I did not experiense much gain in MPG, maybe at best one to one and a half MPG.
went on a lil trip of about 400 miles last weekend. got 18.3 mpg at a average speed of around 63. i was impressed

The rest of the banks get wont help, the exhaust does nothing. He also hasn't reach break in period yet. I would run hypertech on III and see how that treats your mileage.
