They actually did adjust the speedometer for the lift and I figured that into the calculations. it was only about 10% off. I have also heard that I need to tow something in the first few 1000 miles to "seat the rings" will this also help MPG and is this really necessary? The owners manual makes it sound like towing something will help you achieve your top MPG's faster, but dont indicate it is required. (I currently have nothing to tow since all my money is in the truck right now :-) some day we will have a trailer or boat.........some day
