ok, been waiting to post until I got some real mileage figures. Ready to be shocked?
Bone stock without tuner and no power as well.
143 miles, 5.76 gallon that's 24.8 mpg!
Bone stock without tuner gutted convertor, no air filter, new plugs, new upstream o2, 127 miles,4.82 gallon, that's 26.3mpg!!!
New parts, gutted convertor, No air filter 87 tune,178 miles, 8.76 gallons. 20.31 mpg!!!
New parts, gutted convertor, no air filter, tow tune with 70 mustang and 16 ft trailer, 137 miles, 9.71 gallons, 13.1 mpg. 65-75 mph
91 tune, 83 miles, 5.35 gallons, 15.5 mpg!
every test was at 55mph with the cruise on empty except for the tow tune setting. Get ya some of that!!!!
If you own a newer vehicle and you don't have some kind of programmer, your crazy for not! The power difference is incredible!
I haven't tried the mileage setting as of yet but I will be soon.

Looks like you got your best MPG without the tuner

Yes, That is what it looks like, I cant imagine being happy about loosing almost 10 MPG.. The superchips can stay on the shelf...that is just nuts... If my 01 Ram got 20 MPG, I would be sending a thank you note to all the Chrysler engineers...

Set the cruise at 55 mph, don't go up any hills, slow down for traffic or get any head wind and your truck will get 20 mpg but no one drives that way. There are some mods I can tell you first hand will help you get 20 with more normal driving.

 I've personally never experienced nor witnessed a full size truck with a 5.9 get 20+mpg in normal driving conditions..but I guess anything is possible,I'm thinking its just not the norm.
Hey KG is your 99 5.9 truck a 2wd?
I didn't buy the superchips tuner for the mileage, I bought it because my truck is an absolute dog without it. I could drive anywhere and hit a hill or very small grade and it would feel like you had the brakes on! It has the "death tune" in the pcm. When I bought the truck it used 1 quart of oil every 100 miles, had zero power, pinged like crazy. My bicycle could go faster than this thing would. I found the lower intake plenum gasket was blown in 5 different places. I ordered the engine kit from hughes engines. REplaced the spark plugs, upstream o2, gutted the convertor. The rest is history. This truck is a 4x4 3/4 ton quadcab with a 4.10 gear. With the programmer it will destroy the tires in an instant. Without you'd have to jack the rear up to get it to spin!

I'm sorry but I'm going to have call bs on this too. I hypermile the crap out of my '01 360 4x4 1500 w/ 4.10's and the best I can get is 18 at 50 to 55mph. The converter is chopped out, it has a Flowmaster 40 and an electric fan. Also I would have to see this 3/4 ton "spin the tires" (on dry pavement, I'm assuming) to believe it.

My namesake was good for 8mpg, no matter what.
My brand new (at the time) 1990 D150 V6 5 speed got an honest 24mpg day in day out of commuting.
My 97 Dakota V6 auto 2x4 gets just over 18 in commuting.
Tuners are not magic, and if what the OP is saying is true, don't you think it would have become pretty much mainstream knowledge over the last 20 years?
I didn't say anything magic about the tuner and mileage! However the difference in power is MAGIC!!! I will be doing a video soon, my arm is still not back to full strength so it's hard to do things with it. But when I can I'm going to be some power videos and I'll put them on youtube and post a link on here. I'm going to do something with the stock setting and something with the 87, 91 settings. I can tell you I'm currently doing a city mileage test and it don't look good so far. And I'd have no explanation why there would be such difference in the city and highway mileage. I'll post #'s in a day or two.

A chip should be able to net some significant MPG, I have watched the timing curve on my scanner on a lot of these rigs and base idle timing is frequently around 5* advance, WOT hardly sees over 25* and cruise conditions are lucky to get 30*. They seem to have killed the timing to get reduced NOX emissions. I have seen significant MPG increase from advancing the timing, you have to slot the crank sensor bolt holes and slide the sensor to the pass side of the block, you can get about 2* just doing that, you can get a couple more degrees by making the notch in the bell housing a little bigger in that direction. This will advance the timing through the entire curve. If you slide it enough to get 4* you may need some big washers under the sensors hold down bolts.
You can also use fuel injectors from a 4.6 or 5.4 ford, they atomize the fuel waaaaay better so the burn is faster and more complete. Just find a set of yellow injectors on an old ford or lincold in the JY with the same connectors, those ones work in the 92-99 magnum motors.
Another option is a small duration cam that builds cylinder pressure to speed up the burn.
Another problem is the air gets so hot from the intake belly pan that it retards the timing real bad as IAT goes up. Even with 40* ambiant air temps you will typically see 130-140* air flowing throught the runner. Try one of them lifter valley heat shields, an airgap intake or maybe a ceramic coating on the valley pan, anything to keep the IAT down. I tried a 2000 5.9 ram a couple years ago and in the winter with 10-20* air temp it was showing 120* after driving for a while then put on the complete K&N cold air intake and could squint real hard and see maybe 5* cooler intake temps.

4.10s are killing you, running around with no load is making the engine fight vacuum to pull the piston down and friction is a lot higher. It is pretty funny to hear some put hyper-miling and 4.10 gears in the same sentence 
I couldn't believe it would spin the tires either! but it does, with ease. The reason for the superchips was the death flash. I knew it would advance the timing. I will do the slotting of the crank sensor when my arm will allow. If I set the programmer on the 91 setting It won't ping with 87 in the tank with a bottle of octane booster. So my point is even with the programmer, the timing still isn't where it should be. My truck has always been serviced at the local dealership so we know it has the death flash.
