I had a very similar problem with my 02 7.3 while towing my Jeep on trialer. Only about 6000 lbs.
I have Ford AIS (I changed it to AirRaid after the trip), I have TW chip, BB Garrett Turbo and 4" exhaust. I felt the truck could not breath properly with Ford AIS. My mileage went down after I installed Ford AIS. I use to get better mileage with AirRaid.
