Ram doesn't have to prove anything. They will void your warranty if they discover a tuner. Key word is discover. Small to medium claims will fly under the radar, but any heavy engine repair, replacement, or trans issue will require mapping the PCM history and sending it in prior to warranty authorization. Some tuners state that they are undetectable, so the question is are they smarter than the Cummins and Chrysler company engineers that built the truck. Pretty big gamble if you ask me until the warranty is over or you just don't care and can afford a huge repair. The other danger is a dealer with an attitude due to your attitude that reports you.
