What is the IAT Sensor?
I ntake
A ir
T emperature

Sensor... It tells the computer how warm/cold the air is entering the engine...

If you keep your tach under 2K (or 65 MPH) you will get better than 20+ MPG

Headwinds, using winter fuel, running 70+, I wouldn't think 15 mpg is not out of line.

I'm getting around 15mpg (average). Does that sound about right for 4:10's?

20MPG highway, 16-17 City. This is driving like an old lady on her way to church. Normal day to day 17 highway, 15 city. Awhile back I saw an article in some magazine that talked about wind drag. It also tested a Dodge 2nd gen truck. Best fuel milage was with a toneu cover, next was with tailgate down, then with tailgate off and in last place was with a cap. Mirrors make a differance,The mirrors on meant a loss off half of a percent of MPG.

For a 2500, two wheel drive it sounds a bit on the low side. You must have a heavy foot
