I have 5 star and MPT tunes for my 2014 3.7. Current favorite is MPT 93 PRX. It seems the harder you're on the throttle, the faster the shifts, sometimes squawking the tires between gears. If you don't like the fast shifts MPT can change it for you.
Going between stock, 87 and 93 tunes, there's a noticeable power boost with the 93 tunes. The MPT PRX tune hold gears longer and downshift very quickly with a light push. I tuned mine first around 37,000 miles, currently at 43,000 miles. I'm not worried about hurting the engine or transmission.

The 3.7L V6 is also known as "Duratec 37," originally designed by Mazda in Japan back in 2007, and this is Ford's most-reliable V6 engine you can buy today. It is currently being phased out, however, because Ford is not making enough money on parts for it. Stay away from the Ecoboost turbo engines, they're not completely reliable, and you should move on to Chevrolet. Ford wish to make a lot of money on parts after their Ecoboost engines break-down severely after 10 years or so, and they discontinue engines quickly if found too-reliable or not enough dealer service.
