You can read my set-up in my signature. I am currently running PHP tuner in daily driver. Mileage was checked by miles driven/fuel consumption (not off the computer) while driving like an old lady. My speedo is within 1 mph at 65 mph.
My normal commute to work and back in mainly 35 to 45 mph driving and I regularly get 12 mpg.
I recently pulled my boat on a 400 mile round trip to Lake Erie and back. This is a great test for towing because 99% of the trip is dead flat with no hills. I averaged 10 mpg. Never went above 65 mph. My boat is roughly 5000 lbs. and I was using the 80 tow tune.
Don't know if this is related but lately I have been experiencing hard starts in the morning. Had to crank on it 4 different times this morning before it would fire up. Have also noticed on a couple occasions that immediately after start up when I first go to pull away, the truck has absolutely no power and will hardly accelerate. After I get rolling about 75 yards it comes to life.
