That's kind of my opinion on these chips although I have never done any research to make a educated decision.
I have the Cummins 6.7 diesel in my Ram and do stick with the factory scheduled maintenance program. We are very satisfied with all aspects of its performance and I won't take the chance of voiding my warranty by installing one.
