Im a indecisive person

Yea it sux since I still use the truck as a truck quite a bit. Pull a boat, haul mulch, pull our 57 to some shows out of state that type of deal. I am wishing I would of started with the 6.2 but the wife wouldn't let that happen when I bought it. Little discouraging that it sounds like a drag car at this point and wont spin the dang tires unless its wet. I may just throw the 4.56's in it for a while to get my bottom end back and leave it for a while.

Turbo or not, the 4.8 will benefit from the mechanical advantage of 4.56's. The weight of the truck and tight converter will load that turbo more than enough.
