mileage update

I set up a spread sheet to calculate my mileage averages and here's my findings:

Old mileage average for 4074 miles:15.1

Mileage average after PHP for 1565 miles: 16.7

Nice! So far the chip has saved me around $4 in fuel costs per every 200 miles driven.

I've been running almost all at 80 DD setting. Any one use the 65 tow for general driving? What kind of mileage does that give?

Nice!

What kind of driving is that, city, highway or both?

Taking it easy or using the power?

Mixed driving. I have a 20 mile one way commute, then some in town driving for work. A few road trips in there on both averages. I figure with that long of a mileage check I'll get a good mix to compare.
I keep it around 1750 rpms or so on the road as much as possible. I've always driven that way.

I did a bunch of highway over the past weekend.

Truck was mostly empty, had maybe 400lbs in it (people included) and when I calculated mileage, I got 250 miles to 12.68 gallons = 19.7 mpg

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.
