Depending upon what module is updates, yes, an update can affect performance of the vehicle. OTA is just a delivery mechanism to get module updates to your vehicle, no different than if the tech at the dealership had updated some modules using the FDRS system (Ford Diasgnostic and Repair System).
In my three years of dealing with OTA updates for the F150, only once was an update NOT sent via the TCU/mobile data of the car, and that was to fix a problem WITH the TCU that was stopping it from getting updates! So, I highly doubt you've gotten any OTA updates via WiFi for the Mustang.
Nope. I just changed it to something else, then changed it back.

So you've evaluated price increases over time for every other vehicle produced? How did you ever find the time. Care to share all that data and analysis with us? Can't wait to review it myself.
