2002 7.3 ford diesel
 

Anyone installed a superchip tuner in the truck and gained any mileage?

yes...
I have the programmer and if you can keep your foot out of it have seen about 4 mpg gains

super chip
 

I have a new super chip programmer for that truck $300. if you are interested.

I put a DP Tuner with 5 programs, MBRP exhaust and my mileage improved. 19.2 mpg all highway, and 15.1 in town. I have an 01 F250 CC 4X4 with a 4" lift. Love the tuner so much more fun to drive than stock.

I second the DP Tuner. We tried the Edge and there was no comparision.

The 80 HP economy mode is SWEET but it is very hard to keep your foot out of it.

Call Jody at DP and let him do a custom tune for you and you will be very glad you did.

I have the following:

#1 = Stock
#2 = High Idle
#3 = 40 HP Tow
#4 = 80 HP Economy
#5 = 40 HP Tow with Torque Converter Lockup braking
#6 = 80 HP Economy w/ Torque Converter Lockup braking

The 40 HP tow will run circles around the 60 HP Edge. I've run it three years now and 30K miles now in an 02 Ford 7.3 PSD with nothing but a smile. It's all switch on the fly.

Good luck

I've got a 2000 Excursion with the 7.3, and also a Superchip, and its pretty sweet! I've got mine up 80 horse. If you go over that you have beef up the rear end. But, yeah, it definitely helps with mileage.

I've got a 2000 PSD 4x4 CC Dually with the Bully Dog 6 position chip. I don't think I really saw any significant mileage gains with my chip.

You've got to free up the intake and the exhaust to really get full use out of the right tuner. If I do it over again, I'm going with a DP setup. The fact that you can order it ala carte with the settings you want is awesome. They get great reviews on all of the diesel sites.

My '01 7.3 has an ati filter , good exhaust and a superchip. Drastic improvement over stock.

B One is yours brand new with all the paper work? Why are yu getting rid of it, did you not like it?

Which is better and why the Super Chips with it 3 settings or the DP Tuner, and why. Does the super chip make more power with its top setting of 110hp and 200lbs of torque than the top setting on the DP Tuner? I think the super chips settings are 40, 80, and 110hp. How much is a DP tuner?

Just check out the DP Tuner site:

http://www.dp-tuner.

The best part is its not "one size fits all". You can order each individual setting that you want/need for your application.

Had an 01 F350 4x4 with the 7.3 in 02/03 and used the Superchips tuner in it and towing 5000 lbs at 80 mph averaged 18.2 and ya know by now that the programs have been updated/improved.

My wifes truck hauls ass with the DP tuner. Trans shifting is a little harsh for horses though!

I have an '03 7.3 stock I get around 13 14 normal driving. You guys posting 19 is that for real? Are they otherwise stock. I don't like them loud. I don't need more power by 19 sounds awesome.

I have the DP tuner too. Do not spend money on the antiquated Bank's stuff. They are just a simple raise in injection pressure... you can do the same with a 5 cent resistor.

For the 7.3 the DP tuner is the way to go, you can select what ever programs you want. you could only do 3 if you wanted, though most of us have a few more fun tunes. I also like the fact that if I remove the module on mine, it goes into a no-start mode. The truck can not be driven away and stolen at that point.

Shooting out black smoke in the high tunes is fun for tailgaters... not that I condone that type of behavior :)

Also get gauges.

For what its worth, I upgraded from a super chips to the DP-tuner. I will never go back. shifting tunes on the fly is awesome. I was caught out in very slippery conditions, pretty much black ice everywhere, and being able to flip the switch back to stock was a life saver.

With my tuner I get 14.5 around town.. thats with 4 inch lift, and 315 tires. On a 60mph back road, I'll get 16 mpg. I kept track of every tank since I've owned my truck.

I don't know about 19mpg on the highway, but he is in Arizona. The flatness may have something to do with it. There are too many hills here.

DP Tuner only they rock.

96 F250 7.3 two wheel drive here with superchip , downpipe and filter , 3.55 gears , all else stock,no lift , no supersize tires, stock size tires, standard cab ,heavy azz utility bed,
19-20mpg in my daily 80 mile round trip commute
consisting of 12 miles of hills , 10 miles of 40mph city streets and the rest 65-70mph highway.
(if I go over 65-70mph fuel milage drops drastically)
I check it at least once a week , no bs ..
ran it once at track, ran 16.9@83, weighed 6990 with me in it and all my tools in the back. :)
I would push it off a cliff if it only got 14-15mpg! :D

my mileage went down to 13. My HP went way up love the hp, but I put a chip in that a friend had mpg went to 21-23 maybe 35-40hp increase. I like the fuel mileage so I going to sell the programmer. I don't know what brand the chip is I wish I did works great.

Let me share something with you that I designed. I took a line right after the pressure drop on my a\c were the line gets cold. Made a coil, put it in a box, after the innercooler and before the intake manifold. The air comes from the innercooler goes through this superchiller then into the intake. This thank is great it make the truck run the way it would on a cold morning. Increase maybe 50hp. mileage went to 24-28mpg. Cost less than $100 to make.

Are you guys getting your milage from the trip computer or doing the calculations? I hear that once you add the computers the trip computer is basically useless. Or have they fixed that problem?

Trip computers are a guidline(at best), and when you start changing tire sizes etc the onboard computer won't allow for it, so it becomes even more inaccurate, my Edge programmer allows me to correct and show speed but it won't correct odometer readings.

Superchips programmers subsequent to the original 1700 raise the transmission line pressures, which is not a very good thing given the fact the weak link in the 7.3 is the 4r100 trans. The original 1700 programmer is quite good, and can be found cheap on eBay; I still own one and use it on my '02 Excursion. It does not however hold a candle to the DP tuner.
Beware that any performance increases from a programmer or chip can hasten the wear and tear on the trans, and rebuilding them isn't cheap.
There are a lot of 7.3 enthusiasts that have dyno-proven the DP's quality against all the others- they are conservatively rated and Jody at DP can customize a program to exactly what your needs may be.
As far as economy gains, chips aren't the best avenue to increases in mpg's. The tendency is to put more right foot in it because the diesel now drives as good or better than a gasser. Chips DO affect the overhead computer, so the readout there is unreliable. Hand-calculated mileage is the only true test, and I'm a skeptic when it comes to claims of 19 mpg's in a 7.3 going 80 mph pulling 5000 pounds. It's never happened in the history of the 444, and never will. Anything over 2000 rpm's drops mpg greatly, and 4.10 gears don't help either. Keep your foot out of it and stay below 2000 revs, and you'll get the best the engine has to offer regarless of performance mods. If you lift it and put on larger-than-stock tires, you can kiss the great mpg goodbye as well.

24-28mpg just by cooling the air? Phase change cooling requires power, so i thought the net output was less than 0, meaning it used more energy than it helped... thus fuel milleage would go down.

Two wheel drive is key to getting higher MPG. You can't compare a 2wd to a 4wd for fuel mileage.

To me, 2wd is useless, so might as well own a Hyundai at that point and get 35mpg.

Now, if I lived somewhere with out winter, I'd probably get a 2wd.

Hand calculated it on a trip from Illinois to Fl towing a 7x14 enclosed trailer, and 3 Harley's, truck had 3.73 gears and 34.5 tall tires with just a leveling kit(2 inch front), ran between 75 and 80 with cruise set.

my 96 doesnt have a trip computer, its bare bones,no power anything and a rubber mat on the floor, its a what a truck is supposed to be, for working . :)
So yes to answer your question I do the mpg by distance/fuel used manually and my speedo is almost dead on at 65mph as confirmed by my gps..

And to me snow is useless so I have always avoided living anywhere that had it. Was born in NY and lived there till we moved to Florida and vowed to stay away from snow as long as I could! :)

This coolant is waist recovery. If you did nothing this coolant would be waisted to the atmosphere.
No I'm also using a chip I don,t know what brand.
Just filled up and got 22.24mpg.
2001 F350 dually std tranny.

4 x 4 will cost you MPG

Dual rear wheel will cost you MPG

4:10 gearing will cost you MPG

I have all the above because I use my truck to pull 12,000lbs and it does a hell of a good job doing it at 10 MPG!:D

I'm trying to follow.. so your not using the AC line? Or are using the AC system? It sounds like you routed the AC line after the expansion valve into a cooler, then on into the truck/back to the normal routing.

EXAAAACTLY,,,only I can go you one better than that,,,,,mine has the Tow Boss pkg. which comes with 4:30 gears, and your right, It does one hell of a job towing 12,000 lbs at 10 to 11 mpg real well. What I found that helped is that I went to 19.5 commercial 14 ply tires on Brentz direct fit wheels.(265/70r19.5) that are 34.5 tall, effectively cuts the gear ratio down to app.3:93. which helps, with the factory tires mileage sucked at highway speeds due to the 31 inch height.

What rear end gears? What size wheels and tires? 4x4?

And the biggest question... was that 22.24mpg divided by hand or by the trip computer on the truck?

I am getting 16mpg f250 crew cab, 3:73 gear, 4wd, stock tires and its a 2002, anyone have a truck like this that they put the tuner in and what did your mileage go to? I am planing to also put 4" exhaust and an intake on it, would love to get 20mpg or better. I talked to Jody at DP Tuner yesterday told him I was going to do a 5" exhaust, he said that that was to big would lose power. Has anyone found this to be true or heard anything about this?

He's right, the 5" exhaust with a 4" downpipe loses torque, we just took one off of my future son-in-laws Excursion and went back to a 4" system with a 3 1/2" downpipe, and it helped the way the truck ran. The 5" is more for the guys running the big injectors and propane. The 5" we removed was a Silverline, and the 4" we put back on was a Banks, the silverline had to massaged to fit around the rear shock, the Banks system fit perfectly,,,,,,,,and he did remove his converter and used the offroad pipe with both systems.
The 4" system, and we used an Airaid airbox system on my 7.3 when I had it with 34.5 tall tires with the 3:73 gears, the truck never even knew the trailer towing the bikes was back there. I never really did a hiway trip without a trailer to say what mileage was. The taller tires helped as much as anything. (10 to 12% taller than stock height)

Also installed a RollnLock bed cover to cut down air drag at the tailgate, not sure if it helped, but common sense told me that at 75 to 80 mph the tailgate had to be causing some drag.

What is the size that tires start hurting mpg? I am thinking that I want to put 35's on with a 4" lift. Is that going to hurt mpg? Anyone have the 4" lift and 35's, what are you getting?

I would be more concerned with power and braking loss.

I had no power loss issue with the 35s and a tuner.

Braking power is not diminished much.

With my truck, tuner and 315/75/16 inch BFG a/ts I just got 13.5 mpg the last tank. Used to be 14.4-5ish, but lost that with ultra low sulfer diesel. Thats a mix of highway and around town. Highway only is higher.

As soon as you change the injector pulse width with a chip or tuner the trip #'s go out the window. Any of the chips are a better solution in my opinion than the Superchips tuner. DP Tuner has a real nice product with a lot of support from the 7.3 Crowd.

On my 04 F250 4x4 I started out with the 315/75r16's (8 1/2" wheels) and got great mileage,,when I went to 325/65r16's (10" wheels) I lost some mileage. Both sets of tires were Toyo A/Ts.

What was your mileage before and after on those 2 different size tires? What was great?
