I'd chalk those initial numbers up to math and the transition to gears mid-tank. Just a couple gallons off. Can you guarantee you had the right amount? It's easy to mis-judge. Also, you have to consider what rpm the engine is operatiing at now as opposed to pre-swap. Not discounting some other issue, but considering what was just done, I mean, it is the 800lb gorilla in the room. For comparison, I have a '93 5.9 with 4.11's and the same size tires as yours, snags 15mpg......if my calculations are correct.
