I get the best mpg from my 120 race tune but it all depends on the skinny pedal

MPG's can vary wildly. As mentioned above, the skinny pedal is the best way and 1st consideration when looking to gain MPG's.
Despite what tune is loaded, overall mechanical condition is the 2nd consideration when looking to gain MPG's. Tires, sensors, exhaust drive pressure, intake, intercooler boots, etc... They all play a little part in achieving a well running 7.3L.
Although, sometimes "good" MPG's are just not in the cards no matter what the owner does. I am lucky and get 18.5 unloaded and 11 - 13 MPG's (both hand calculated) at 18,000 - 20,000 GCVW while towing a 5th wheel. Others are not so lucky and struggle to get 12 MPG unloaded. On the other hand, several see near 20 and at least one prominent member here with an Excursion gets 22 (maybe it was 22.5) MPG.
We are not saying that you cannot or will not reach your MPG goal, but with a 8000 lbs vehicle, you will have to be mindful of the mechanical state and the angle of your right foot when driving.

There is one way that absolutely 100% guarantees approximately 20% better mpg, move to the UK....although the fuel prices here are eye watering compared to what most of you are paying, the Finlander is probably paying similar prices to me too....
