I took my 70D in to get the LTE upgrade and I got the best range ever on my 90 mile return trip home. I have 2,600 miles on the car and I've never come close to getting the range indicated on the speedometer. For the trip home I got 260 Wh/mile when my norm is around 350 Wh/mile. I started out with 209 miles range and after going 90 miles it showed 119 miles range. Could they have found something wrong, fixed it and didn't let me know?
