Soon to be full timers but a question re: 6 speed gassers

I can say that our 2016 w/6 speed transmission is a good one. Then I will tell you that based on my past experience with a Ford P?U and after reading many reviews and posts , I bought a 5 Star tune and there is a very pleasant difference in the shifting and manners of this unit. I had seen many good reviews on this for the 5 speed traany as well. I paid $499 for the tune and I feel it is worth it. I tow just under 4,000 lbs. Happy hunting
