Thoughts on a tune
No reason to not do it if you want it. My 2015 has been tuned since about 6 months after I bought it new in March 2015. I mainly wanted to get rid of the abysmal OEM "hurry up and shift into the highest gear possible, as soon as possible" transmission tuning. I bought 5 Star tuning because they had a reputation for spot-on transmission tuning, which turned out to be true for me. The discount I received because of a group buy was the icing on the cake.

Lots of tune companies to choose from. I've done a few with very good results. My favorite in Gearhead Tuning, they us an off the shelf variable octane tune 87-93, so any available pump fuel will be adjusted to. Bigger is the transmission tuning is top notch. Remember to specify to the tune/programer what you want in the transmission tune. I wanted additional shift pressures of +10% for quick. firm, solid, shifts, GH hit my request right on the head! I feel a tuned transmission adds a lot to the life of an automatic transmission.
Side note I am wondering if my tuned trans would benifit at all considering the current re-progaming recall. I think the recall would do nothing for my transmission as I would just re-install the tune anyway. KM

Thank you for the replies. I hadn’t considered a tune for the trans. I was thinking of the hp gain on motor. My only experience with a tune is on my VW R32
non turbo v6 and tune gains are 10-12 hp. Was always jealous of hp gains on turbo motors. For the 3.5 ecoboost I saw 100hp gain from tuner website. Could have been stage 2 numbers. Nevertheless would be much greater than 10-12hp. My concern was putting a tune on a motor with 97k. It would be a given that the motor would need to be in good relative condition. I take the tuner numbers with a grain of salt. The old your results may very type of thing. .

An Ecoboost tune can add 100HP/torque, these engines really respond to tuning! Even the off the shelf AO tune I have added near 100 more, a custom tuned and revised on 93 octane even more, without any other mods. KM
Running a 5Star 89 tune since I bought my 15 with 70 k mi.
Now at 111k mi., Ocasionally load the 93 tune but I believe the 89 tune is a nice compromise of performance and operating costs.
You may want to see if the trans tune is included with an engine tune, pretty sure it is but I could be wrong.

Not a 3.5 but I've run tunes on several of my trucks
- 2004 F250 diesel. Used Gearhead Performance SRL. Really woke the truck up. Ran a 13.86 @ 96 at the track.
- 2014 F150 5.0. Started with 5Star (was fine, no issues), then switched to OZ (complete disappointment), then swapped to MPT. I like the MPT the best.
-2018 F150 5.0 (current). Waited until MPT finally released support for my model. And wait was worth it, good power/response, got rid of the skip shifting BS on the 10 speed, and the MPT AAA works with the FlexFuel system so one tune covers all fuels - no need to swap tunes based on what's going into the tank. It will adjust as you go.
