If this was asked before I apologize but I couldn't find it anywhere. I was wondering if there is a need to put my 2015 in sport mode if I have a tuner (livewire tuned by 5*) since the tune will change the shift points itself. Is there anything else that sport mode would add to the truck that the tuner would not? I currently have the 93 perf tune on it. I have the 3.5L eco 2wd

Not sure... Good question

I'd ask your tuner. I asked mine the same question & he said sport mode would be slower--I'm talking about 1/4 mile times.
