The tuning information isn't anything crazy. It's really just whatever modifications you may have, tire size, your truck's axle code (which is located on the driver's side door), and your PCM code (which is located on the computer itself). If something were to happen, you take the truck into a Ford dealership, and if they don't cover something, you'd immediately call us. We'd then send you a claim form and work with your dealership's service department after we've received your form back.
