agreed....truck might shift a little hard/ speedo will be off, but if it gets a lot better, there was probably a mix up in one of the tables.
What size tires are you running with a gear that big? Make sure you measure from the ground to the top of the tire when installed on vehicle, and send him that measurement for the diameter. A "36" can measure anywhere between 34 and 37 inches depending on brand. When getting in gears that big, any difference can make a big difference in the calculations for shift points. When I went from 3.73 to 4.56 my speedo was WAY off on the ride home until I threw in the new tune.
blown transmissions are about as useful as 97% of the guys on this forum
