Just for clarity, the addition/modification of the oem PCM programming/setting
MAY void your warranty for the items directly affected by that change. There is a consumer protection law that requires the manufacturer to show how that change caused the premature failure of the affected part(s). With that being said, the cost of battling the deep pockets may cost more than fixing whats broke yourself. What it does not do is void your entire warranty so if you are confident in your ability to deal with the issue and you know where to take it for service, you will be fine.
Also noted is the vehicle and type of tune. The application of the tune on the 6.8L V-10 is quite different then the diesel application. The topic pertains to motorhomes only.
