Well before I leave on my road trip, I want to make a good custom tune that will give me good mpg (for a f150) for fast highway driving. Basically I'm going to be going a constant 75mph or more for awhile.

I've noticed before that I take a major hit in fuel economy when I go over 60 mph. Is this because the ford tune and canned edge tune is revolved going around 55mph (the average driving speed for highways).

What would be a good tune.......perhaps messing with the gears and **** points?

Oh yeah, i'll prolly be running at lvl 2 on 87. I may fill up with some 93 when I come home

 

I have played around a bunch with the settings on mine and i have found that if i bump the timing to compinsate for 91 octane fuel and run level 2 that i can get better mpg. This at a price of 5 or 6 bucks more. It comes out to about the same cost per mile but i have way more power.

When im on the highway i prefer to run level 2 becuase i can feal a torque differance. I dont have an automatic so i dont see the differance in shift points but thats my 2 cents.

I dont have a clue what engine you have but her are my settings for my 4.6 that seem to do the best for me.

level 2..... 160 WOT..... 91 octane.... bump the timing up 2.0

 

i have the 5.4
