No BS...What is your fuel economy: Excursions

I have a 2004 6.0L 4X4 Excursion with ~ 85K miles (newly purchased). I bought the thing to for the space and the f/e (vs. buying a newer Yukon/Suburban gasser). It is now riding on 33" tires with stock suspension (vs. 37" and 8"lift kit - for sale by the way). My fuel economy on the highway is right at 15mpg (meter/hand calced) drivng ~75mph. City is just a bit less. I have changed: oil, fuel filter, air filter and I am on my first can of fuel additive. At this point I am considering tuning and even a gear vendors overdrive unit (pricey but considering it). My wife and I love the truck but I thought mpg would be better.

What fuel economy are you guys getting (average, city and highway @ what mph)? I am just trying to figure out is something wrong with my truck, were my expectations to high, etc.?

Economy

Have a 2004 limited 4x4 with 2004 late year motor. Got 15-17 mpg going from central KY to okaloosa island and back. About 60% highway and 40% city. 75-95 mph, 4 adults, 2 kiddos, and a large "coffin" on the roof. All extra room packed to the gills for vacation. Also depends on who is driving. Wife gets avg 1.5-3 mpg less than I do. We get @12-13 in town, Home hwy @15-16.

dont know what mine is never really cared enough to figure it out. I am going to put diesel in it regardless. If i am going on a long trip i try to stay under 2k it saves the fuel gauge from moving down as quick.

Did a bit of testing today...tried cruising highway at 60mph or 1600rpm...car did 20.5mpg over 20 miles. Looks like my engine likes to operate below 1600. Looks like I need to invest in a gear vendors unit since my wife likes to do 70-80 mph on the highway. I cant believe 10mph or 500rpm makes that much of a difference.

yeah, on the highway once you get above about 2k RPM the fuel economy starts to drop off significantly.

You might look into lowering your final drive ratio by changing gears. I'm not sure what is in your Ex now but if you have 3.73 or bigger then you can probably go smaller and get better highway mileage, and it'll be cheaper than the gear vendors unit.

You might also consider running an SCT tuner with a hot race file (custom file) on your long trips provided you're not towing anything. If you can keep your foot out of it, Ie: no hot rodding, you should see a couple mpgs gain from that alone. In my experience just adding a tuner and running a low power file doesn't do anything to improve fuel mileage, but running big race files and taking it easy will do wonders. Also FWIW, I've seen about a 1 mpg increase just using diesel kleen fuel additive from powerservice.

Its hard to tell by the various posts on this site, but who are the good tuners/vendors purchase an SCT/Custom files from?

I run Innovative diesel tunes which are great. I've also heard great things about Matt Robinson's tuning at Gearhead automotive. Those would be my two top choices based on tuning and customer service.
