The last article I read about most of their piggy-backs was that most read over 175 inputs and made the modifications to the stock ECU. That's more tuning than most.
I am not even sure you could call the warranty a relationship between Dinan and BMW, other than they might get better parts pricing and shop rates than someone off the street when an engine goes south within the OEM warranty period.

Can you point me to the article you read about their piggyback tune?
