i was experiencing the same issue, under 2000 miles on the truck, terrible MPH
Limited, 4x4 5.7 with 3.92 gears 20x9 oem wheels.
stock 18.5 mpg on the hwy was the best ever seen.
Made a few changes and seen an improvement with each.
*bumped tire pressure to 44 psi.
*drop in k&n with carbon filter delete.
*Flowmaster large Rv muffler Super 50 #53057 with a cheap 12 inch resonator before it (perfect Btw for guys wanting quiet cruise even with MDS)
keeping the truck under 74 netted 20.7 calculated. and dash was very close , must drive conservatively to do so.
