Fuel Mileage

What should I be getting? 08 CC 6.4L with 325x60x20 Nitto Terra Grappers on 20x8.5 KMC XD Spy Wheels. No lift. I went from about 13mpg to 8-9 mpg.

Plan on buying a programmer ASAP. What should I buy? I tow a 16 ft trailer with fourwheelers and a 22 ft Wakeboard boat that weighs about 4K lbs.

Any info will be greatly appreciated.

What are you basing your mpg off of? Did you get the speedo recalibrated or using a gps? I ask because if you changed tire size your odometer and speedo are off. I was showing some crazy numbers from the lie-o-meter in the dash but had no idea until I got my speedo working right.

The truck hasnt been calibrated or anything yet, so I know the numbers arent accurate. Just wanted an idea from all the experts on what I should be getting.

I asked because you said you lost almost 5mpg and that doesn't sound right. I lost about 2mpg going from my stockers to 37's on the factory 20's. Given my daily driving routine I'm getting about 13mpg. That's a 18 mile run from my house to base doing 60mph and the little bit of driving I do around town getting the kids from daycare and putting around base. My truck is stock.

Yeah, mine really dropped off alot. What do you do in the Air Force? Where are you stationed?

I talked to a diesel performance shop here today and think Im going to go with the H&S Black Maxx, 5" exhaust from the turbo back and an intake.

Dont think I need all of that, but for around $1700 installed for all of it, dont think its too bad of a deal.
