I have recently purchased the Edge Evo and am very inexperienced with the custom tuning. Does anyone have any suggestions for custom tunes which will maximize MPG'S for strictly highway driving.

 

Set one of your gauges to monitor instant MPG. Your best chance for milage improvements will be changes/optimazations in your driving style. Finding what HWY speed, throttle position and RPM gives you the best HWY cruising gas milage.

 

The only tuning option that might do anything at all is turn the shift points earlier so the truck is short shifting itself. There are no settings to lean the motor for good reason. Best mileage you can get strictly highway driving, slow down, if you could possibly hold you speed around 60mph you mileage would jump way up.

 

ok will give that a whirl...thanks!

 

I got my best mileage on the highway running a custom level 3 tune with the timing bumped 1.0* and 93 octane fuel. I got 16.75 mpg running 90 mph. Wish I could do that in my Superduty.
