There is a hidden feature on F-150's called "Engineering Test Mode." You can change certain features within this mode and the fuel mileage calculation is one of them. The link below has good info on how to make the change. Post #60 is a good starting point. It does take some trial and error to get the truck into test mode unless your lucky the first time you try. I was not but I figured it out. ForScan isn't needed, the tool built into the truck. I've only changed my fuel calculation but you can google "Engineering Test Mode" and get much more info if you want to delve into it.

This link will show you how to calculate the number to enter to achieve more accurate MPG numbers.

I bought my 19 raptor used at 5900 miles and was only able to squeeze 14.5 MPG according to the trip computer, and I drive very conservatively. Just filled up 33.5 Gals and computer estimates 490 for this tank. I feel like this is not normal, any thoughts?

Mainly drive in normal mode w steering set to sport for heavier input. I don't drive in sport or like an ******* all the time as I don't like buying tires every 20k.
