16,036 miles worth of data on the Tahoe. My best guess is a 60%/40% mix of highway/city. Here is how it breaks down:
Before Tune:
15.72 Average for 87 Octane
15.63 average for 89 Octane
15.70 average for 93 Octane
Combined average - 15.35
After Tune:
15.97 Average for 87 Octane
15.63 Average for 89 Octane
15.61 Average for 93 Octane
Combined average - 15.86
Max - 17.62 mpg
Min - 13.02 mpg
I wished I had what some of you people are smoking....or burning for fuel. I cant even dream of 20 mpg highway. My Tundra has come much closer to accomplishing that (19.33).
