I have realized a 2.5 to 3 mpg average drop in the cold weather. These trucks seem to be very susceptible to cold weather. I imagine your mileage will improve with warmer temps.
Thanks. Engine was well warmed when I reset mpg computer just before leaving dealer. Air Temps were 25-33 deg on this trip, no wind. I checked engine temps during trip and was settled slightly higher than mid range on gauge (if that means anything).
I have an appt with Ford Service center in town lat next week. For what its worth, this morning I called and spoke with the sales mgr where I purchased the vehicle yesterday. I told him the situation. He went through the normal checklist of considerations including blaming it on low octane gas they filled it up with (87). In the end he said it's just not right and to keep him posted after I have the tires checked at Schwab and engine run through at the local service shop. I did notice for the first time today that on 4 occasions when pulling away slowly from a stop that there was a loud "thud" when the engine shifted to 2nd gear. Am i to assume that the transmission is failing, or? I do have 8 mos left on the bumper to bumper at least.

so if you don't do any kind of off roading or seroius pulling i would see about going back to the factory size tires and a lower ply rating if possible

Hand calculate the mph instead of using the pc. At least do it for 1 tank

My 13 f150 gasser gets 20+ on the highway too if I drive it right. See I can say it too.
I would put a lot of it on the tires, recalculate the mileage by hand, unhook the battery for an hour to reset the PCM, and look into the spark plugs being gapped correctly. I would also ask the dealer to verify which PCM programming you have to make sure they didn't neuter it for a inter cooler repair. You should be able to look at the inter cooler though and tell if it's had any updates done to it.
You might also check the quality of fuel being out in the thing ie heb brand vs texaco. My family used to have a Cadillac with the North Star v8 I believe, and if you ran one brand of fuel too long it would get hard to start and the fuel mileage would fall off until you ran a different brand for a tank or two.
You also need to factor in the added size of the tire on your mpg, especially if you're just going off the PCM. It's calculating figures based on the wrong ratios.
