Same here HP is less than I would expect. I may just delete that one. Was more of the coolness to try it. I may have gone WOT 5 times in 5000 miles
I only have current mpg as an X
I use trip Current and the reset, to help me see how it's going when doing something. It's very helpful. Try it.
I have yet to see one user that can look at the instant MPG and say it's this or that when driving. It's just all over the place. The X gauge Current can't be reset from the gauge view but can in the Trip view.
