Mileage Update
I have a 2002 Excursion 4X4, lifted - 6" and running 31575R16 tires plus other engine mods - below is my info:
Overall Miles: 82,300.1 Avg MPG: 14.57 Best: 18.66 Worse: 11.27
Stock Miles: 21,943.6 Avg MPG: 14.03 Best: 16.17 Worse: 12.38
Added Lift-Tires, Exhaust etc plus
Edge Programmer: 11,217.5 Avg MPG: 13.25 Best: 16.95 Worse:11.27
DP Programs: 40,282.5 Avg MPG: 15.02 Best: 18.57 Worse: 11.62
PHP Programs: 8,856.4 Avg MPG: 16.01 Best: 18.66 Worse: 13.25
When I did a local 1200+ Mile test: I averaged 15.95 in the 80DD, 15.78 in the 100P and 16.32 in the 120R. The lie-o-meter is almost spot on in the 80DD and 100P but is a constant 1.4 High in the 120R. I run the 120R 95% of the time.
