In 2016, Ford upgraded the transmission on the Titan V10. That being said, we are on our 3rd Triton V10, dating back to our first one in 1994, to our recently retired 2009 with over 200,000 miles, to our new to us 2014 with 45,000 miles. All towed our 24ft enclosed trailer filled. The v10 is designed to run high on rpms before shifting. Before installing the tuner, you should see if it's really necessary with the transmission change by Ford.
