I'm sure it's in one of these threads somewhere, but I know this will void the factory warranty correct? Is there a way to put the factory tune back? Or is there no going back once it's done? Can they tell?
Your warranty guide will explain what is and is not covered.
Here is an excerpt from what is listed under things that will not be covered;
Damage Caused by Alteration or Modification
• the installation or use of a non-Ford Motor Company part (other than
a certified emissions part) or any part (Ford or non-Ford) designed
for off-road use only installed after the vehicle leaves the control of
Ford Motor Company, if the installed part fails or causes a Ford part
to fail. Examples include, but are not limited to lift kits, oversized
tires, roll bars, cellular phones, alarm systems, automatic starting
systems and
performance-enhancing powertrain components or
software and performance ‘‘chips’’.
Not sure if this addresses your concern or is relevant with what this thread is about.
