It's the New Guy with the low mileage 2015 RAM - on the advice of my "diesel consultant", I have selected the engine (exhaust?) braking option for my GDE tune. And now I'm having second thoughts after 1) seeing a thread in this forum where an individual experienced some turbo-related damage and pointed the finger at this GDE feature, and 2) doing some reading that made the case for poorer mpg performance if your driving has a lot of off and on throttle (typically elevation changes related). On this 2nd point, I did see some suggested work-arounds (keep foot lightly on gas and it won't activate...). ANYWAY - feedback is a gift - should I with the option...or not? Thanks.
