Hope you see this.
I've been using Race Chips (from Germany) GTS Black series tuner, since 2018. First on my '14 Fusion 2.0 ecoboost, and now on my '20 Nautilus 2.7. It's simply plug and play, has multiple settings as well. It does require 91+ octane gas. The GTS Black comes with downloadable app interface, which makes it user friendly. Race Chips has an extensive You Tube video collection, covering a wide range of their offerings, with before, and after, test runs. You can check out some videos, and see what's up. Good luck.
