Does my computer compensate for elevation?

    Previous owner used to haul heavy loads, so he put an AAL on it and TRD front suspension with a lift and custom rear suspension for added weight capacity. I recently installed a tow package (Curt with lifetime warranty) So i will definitely see what this thing can handle as far as weight goes.
    i am moving to high elevation (about 8500 ft asl) I have the 4 cl and am worried about power loss. My father, who is a master tech, told me getting a high flow air filter is a waste of money and to keep it the way its built to be. He believes that the more you change things around the more problems you will have. He told me my truck has a float that compensates the elevation change. true?

    Not as many as the 98..
    Your truck is EFI, no float. The MAF compensates for airflow and density that comes with elevation changes.

    So would a high air flow filter or a cold air intake benefit me? or would it be a waste of money? Not trying to make my 4cl fast. Just maintain the power it should have.

    There is a difference between having a restrictive filter, or whatever else, and not having enough air density. Can't really bring the density back at high altitude.

    I drove to the top of mauna kea (13,000 ft) a bunch of times, with the stock air filter and with a aftermarket drop in and notice a whopping nada change in performance between the two
