@Wayne64SS

your mileage is definitely off. i was getting 14mpg towing in my 99 7.3 zf6 dually truck. got about 16-18 unloaded depending.

it shouldn’t be smoking under WOT unless you’re under the turbo. How many miles are on this? What’s your air filter look like? I’m sure I can fix it, the question is do you want to pay me.

Yes under boost and 160k and air filter is airaid or whatever. Probably needs cleaned/replaced.
