Has anyone here purchased a unlocked pcm and diablosport tuner and installed it on their 2015 or newer ram. And later put the stock pcm back on for dealer warranty, and the dealer could not tell you had it on, when they had it on there computer?
Thanks

all they can see is a reset as in a battery disconnect. the mileage will be different if they look hard enough
