How many miles on the truck??
I'd highly recommend cleaning your sensors and resetting the ecm at the same time. Just unplug the battery hit the high beams a few times and while it's out grab a can of contact cleaners from the local electronic store and clean the 3 primary sensors... Mine were super oiled up and dirty. I did this when I had a similar mileage drop putting in 91 octane... Running 22-23 mpg in the freeway with 91 on my current setup now
