Anyone using them? If so, what is your experience with them? The automotic octane adjusting tune does not producer the maximum HP gains w/ 93, but I like the idea that I don't have to worryu about what "tune" is running, and absolute max pwer gains is not as important as driveability and being safe(r) if it gets filled with lower octane fuel. https://www.ghtuning.com/product-category/ecoboost/2015-2021-expedition/
