If you were in the dirt and running hard you would love sport mode. It keeps your “R’s”up so you don’t have the tranny searching through the gears so much. I’m sure you know this so why are you complaining about your truck working as designed? Wrong environment for sport mode. You want a more responsive throttle get a peddle commander or tune.
I have to disagree - Sport mode is for the street. Traction Control is really going to **** with you, and if it's a 19, the live shocks will too. It stiffens up the outside shock to prevent body roll in when corning in Sport mode, and that is *definitely* something you don't want on the dirt.
