Just checked the window sticker and I do have 3.31 gears. And I definitely won't be changing gears although it would create that higher RPM in the range that I am getting the bog but not worth it in my opinion.
I do lock out 5th at times but in the flat areas where I would like the low rpm for them good MPGs I have to up shift Mehhh..!
And driving the sport mode I'd rather not like said again rougher shifts and trans breaking.
Just like the lazy driving most of the time.
And it's not always at that speed and gear I do get it at other speeds and gears. So something needs to give
I contacted 5star they got back to me this morning. Their reply was our tire "SHOULD" take care of my issue but when I do decide to go with the tune to mention my concern to have them look at that area more.
I guess either way tuning the truck can't hurt either way

I didn't think the 2015's had the sport mode and only started in 2016. Maybe i am confusing with something else.
I agree that it isn't the rear differential's fault on the bogging down issue. Mine does this as well and I either put in Sport mode or lock out top gears. My current truck as the 3.31 and my previous F150 had the 3.73. Both bogged down in the same spots. So as already said I think it's the shift points. Either just keep it in Sport mode (if equipped) or get a tune.
