What type of wagon do you pull?

 

What was it before? Any major changes done before the drop?

 

Many factors actually. Weight your carrying. Cold weather. Trucks regening if like crazy going down the road. Improper inflated tires. Headwind. Drag on the wheels. Maybe even your driving habits.

you have to eliminate that list to see what the issue is.

 

Governed at 75 has nothing to due with it if you're not running it there all the time.

Check the basics, no boost leaks anywhere. Check for black soot all around the manifold/turbo. Pressure check CAC (charge air cooler) if you can. A boost leak will make a high pitched squealing noise.

Check engine light on, any codes?

Also with the winter blend fuel it's down about roughly .5-.75 maybe even a hair more

 

I get 6.5-7mpg but usually weigh in around 73-80k gross.
