I haven't pulled with it too much yet as I just bought it last fall at the end of our roofing season. I used it once stock pulling a 12k lb trailer on a 500 mile round trip in heat going 75 mph and had no problem. Then did the add ons and immediately started pulling the 0088 code. It does seem like it happens when cruising 70-75 up a grade and then it goes limp. If you restart it, it goes back to normal, but only for 5-10 minutes, then limps again.
Speed may make this worse. If I drive 60-65 the turbo boost is at the halfway point. When I go 70-75 it goes up to 3/4 plus on the gauge and then pegs it if climbing a hill. And the mileage goes down more then 10% with the speed increase. The 4.88 rear end is lower then I need for my tow load.
I did all of this to improve my mileage, but I haven't seen much of an increase. This is an everyday work truck that I must depend on. Im about ready to put it back to stock.......
