One of the " FEATURES" of the GDE tune is constant 14v charge from the alternator, gen 1 and gen 2 stock did the same thing where you would notice battery voltage drop to 13v while driving, I am gde tuned and noticed the battery reads 14v constant as long as the engine in running..

I wouldn't be surprised if FCA took it to next level with the gen3 in order to achieve better mpgs.
