A software fat finger on some chassis cab tunes.....well, that is a different matter, not to be conflated with lack of alignment and poor coatings on lifers.
It's easy to say how bad something is without understanding it's intricate part in a very complex set of engineering parameters and operating conditions.
Needless complexity really doesn't exist in these trucks, Ford is too cheap for that.
