I went to my dealers website and looked at the Morronies (window stickers) of the 2020 Rams currently in their stock and did not see that listed. However, the 5.7VVT engine is listed at $1495. On the window stickers you're seeing, is there also another charge of $1495 for the engine?
I'm suspicious, for a reason I can't fathom an explanation, that the $1495 you are seeing as 'engine calibration flash' is really the 5.7 motor option.
Best regards,
