In the US, the car is only rated for 125 miles, so 127 sounds about right. But the actual mileage you get depends almost entirely on the driving conditions (speed, weather, acceleration, braking, etc). The miles remaining estimation (lovingly called the guess-o-meter (GOM)) will change based on your driving efficiency and state of charge, but it's always just a guess. So you'll see different miles remaining, even at, say, 100%, if you've recently been driving quickly or slowly, for example.
So a dedicated Level 2 charger would not result in a higher mileage estimation unless you were charging it to a higher percentage.
