I have an 06 6.0 4x4 and have installed the hypertech programmer and have seen my mpg drop from 14mpg avg to around 13mpg on stage 3. Now i know most people will think I keep my foot in it all the time, but this is not true. Under normal driving situation I would think my mpg would be better even before the hypertech programmer. My 04 6.0 avg around 17 mpg. Does anyone know what the difference might be? I would also like to state that my onboard computer states i am gettin 19mpg with the hypertech but it is only 14mpg. Without the programmer the computer is spot on. I feel like hypertech is deceiving me by tricking the computer to calculate a higher mpg. Any opinions would be greatly appreciated

 

I just bought one and it won't even load. It gave me an error and said to call them. I think I might send it back to where I bought it...

 

If you expected a Programmer, Chip or anything that boosts the HP and Tg. to get you better Fuel Mileage You don't understand that it take more Fuel to to get that Extra HP and Tg. I've yet to see any get a truck or car better Fuel mileage!!

 

Actully, you should be seeing better mileage. They arnt tricking your computer to make your display read higher MPG. They are tricking your computer so your 6.0 can put out more power. I think pretty much all of them read wrong on the overhead display. You must hand cal. to be acurate.

 

The computer reads 14mpg stock and also calculates to the same when i calculate it by hand. When i have the hypertech installed the computer reads 19mpg, but when i calculate by hand it still is 14mpg.

 

i have a 2000 f250 v-10. mileage before hypertech tuner-12.1 city, after hypertech tuner- 13.3 city.

 

Not true.

Most tuning devices make power more efficiently, with less engine load.

I'll keep this response short because this is an over-discussed subject.
You are making an outrageous claim when you really don't have any research to back it up.

Did you know that many vehicles make power running LESS fuel than stock, even at WOT?

Even my 06 Audi Turbo, while making 50 more HP with an APR flash, still gets 2 MPG better than stock overall.

Granted, most "Performance" diesel tunes will only yield mileage gains if you aren't flooring it from stoplight to stoplight. But remember, thats a new "learned" driver behavior due to increased power.
It's kind of like a new relationship....you tend to "wear it out" for awhile. =o)

Calculate stock mileage.
Calculate tuned mileage. Even if you step on it every now and then, you'll be surprised what you find.

Nevermind the overhead "lie-o-meter". It tries to calculate fuel consumption based on load (and other factors) and when the truck is tuned, it has trouble calculating.

I'll close with this:

Do some research.
I spent years tuning gas and diesel engines, testing, tuning, monitoring calculated engine load, hand calculating mileage (going so far as to weigh each batch of fuel for specific gravity consistency).

Forgive me if I'm being a little harsh on you , but you were quick to jump on a soapbox and tell someone what they don't understand.

Nothing personal, just do a little more research before you jump to your "logical" conclusions.

Please don't take this personally, I just can't stand misinformation.

 

“You are making an outrageous claim when you really don't have any research to back it up.”

Let’s see my Research, 100,000 miles on my totally stock 01 7.3 it averaged 17.152682 MPG. At 100,000 miles I installed a Hypertech Power programmer III, Fuel Mileage on First tank was lower as was the Second, Third, Forth Fifth and so on!! Over the next 100,000 miles the fuel mileage dropped to 15.993861 MPG that is the total average for all 200,000 miles the second half 100,000 miles to 200,000 miles was even more dramatic At 14.897957 MPG!! Truck was totally stock, until 161,000 miles, at that time I put Wider Rims and Tires on it!! Mileage went down then also! I put a lot of miles a year on my trucks and I’m a little **** about Fuel mileage.

No one and I mean no one I have ever talked to in person has ever claimed that a programmer has ever made their truck get better Fuel mileage!! On the contrary to a man every one of the people I have talked to has stated the programmers have decreased the Fuel mileage!!

I’ll close with this:

Do some research?

I spent years Driving gas and diesel engines, monitoring, hand calculating mileage.

Forgive me if I'm being a little harsh on you, but you were quick to jump on a soapbox and tell someone what they don't understand.

Please don't take this personally; I just can't stand LIES and misinformation.

I will state this again, Programmers, Chips, Etc. will NOT get you better Fuel mileage!! More power Equals More Fuel. You can add small amounts of Power 1or 2% without more Fuel but that’s about all!! After that it’s more Fuel and more money!!

 

Your isolated "experience" in one truck with one programmer on on particular tuning strategy applies to everyone?


Have you ever tuned a diesel truck, performed any kind of controlled mileage test (including weighting the fuel, measuring flow, etc..)

Can you explain what calculated engine load is? Can you put together a working injector timing curve?

Do you understand you can add power (significant power) while still inducing less engine load at cruising speeds. even while towing?

Do you understand what calculated engine load and VE are?

Have you tested multiple programmers on many different trucks and tracked mileage trends?

You are misinformed and inexperienced in this matter.

Theres a saying I used to use a lot:
"Talk what you know".

I don't tell an architect how to design his buildings, and he doesn't try to tell my what I don't know about tuning and fuel mileage.

Again, I'm not talking down to you.......but you are making comments in an area out of your expertise.

 

IMO , If you are buying a tuner to increase mileage. You are buying for the wrong reason. These chips are sold because of hp and TQ gains. They advertise the extra fuel mileage as a bonus.

 

Do your own test and get back with us. Drive 10,000 miles they way you would normally. Then install the ANY Programmer and drive the way you would normally. Please post the Results because some would have you to believe that the Laws of Physics in our Universe can be overcome with the Laws of some other un-parallel Universe.

 

I agree with this statement completly, I have seen many vehicles gain fuel economy by increasing HP numbers. ( as long as you can control your foot)

 

Mobey...My observation of your info shows only one thing. Up till you installed the programmer your fuel mileage was X for your driving style. Then you installed a programmer/tuner. Then your fuel mileage went to Y only because the "Programmer" makes more HP-Torque and the only way to do this is by adding more fuel? Did the truck use more fuel on it's own or was it possibly because you added a programmer/tuner and felt the difference in HP-Torque and kept your foot in the throttle a little more than when it was a stock truck?

I have also owned many Diesel's and put over 150K on the last two...both were programmed with the Superchips 1704 then 1705. For the first tank or so it took me a while to calm my foot down and my mileage came back. I currently have an SCT in my new 06 F250 and I've averaged 18.3 over a period of 9864miles which 90percent is Hwy and half of the fuel comes from Texas (ULSF).

From everyone else around me is getting anywhere from 14.5-16 on their stock trucks.
Perhaps it was the programmer that you had. I always had luck with my Supertuners and am having a little better results with my SCT.

 

I have installed and been using a Superchips programer that was most likely programed by Vic_Ferrari before leaving Superchips since early on with my truck. (I know this isn't the hypertech you have been talking about, but programmers basically all work the same.) I have tested the unit loaded in all stages- non towing and towing vs. stock towing and non-towing. I get on average 3.6-4.0 mpg more towing with the progammer in either economy or performance over stock. Non-towing ranges up to 5.0 mpg better, but that is not common as without a trailer behind the rig, my foot sinks deeper and deeper into the pedal.

Vic is right!
