I have a 2019 and run a gearhead tune, excellent tune by the way. I return it to factory tune, had Ford do the phaser update. Sent the new info to gearhead and they wrote me a new tune. Runs great.
I contacted gearhead, which is the tune I’m running. Was told to load the stock tune, had the cam phaser update done and then sent the updated strategy to GH. Then they sent me an updated tune.
