FWIW each time I have changed the Superchips map on my Edition 30 via the Bluefin device it has usually taken say 50 miles or an hour or two of driving before it starts to give it's best.
It is odd, and I am sure down to the car/weather/fuel/driving conditions, etc .... but every now and then when switching between maps it seems to take to the map almost immediately and just then fine tune before settling .... whereas most of the time it learns and just gets better and better over the next couple of weeks
Mine BF remap has been on almost a year now and no issues at all .... the car seems better too as I've doubled the mileage (to a massive 12K) which can't do the performance any harm !
