Funny you would say that, I have a lot of people telling me this. However, I just don't know if it is a good idea. Like I said I am new to all this so correct me if I am wrong but the truck is driven a lot of city/highway mix. It is my only vehicle and when I am on the highway won't the 4.56 be something I won't like? I was also hoping to maybe gain a few mpg with the 4.10, if I go 4.56 won't I lose a few? I am only getting an average of about 11mpg right now.
As far as reprogramming the computer for the gears, I was almost certain this would be needed. What is the best/cheapest way to go about this? The guy that is regearing for me is a retired local guy and from what I hear, he is good at what he does. However, I asked him today and he said that he has no way of reprogramming the computer. He is retired and has no access to the shop where he used to work.
