Has anyone tried this thing clams you will get 4 to 7 MPG better mileage.
thanks for any info.

 

Lots of legal "dancing" around on their website. They're very careful not to say it won't void your warranty. Instead they call it "warranty friendly". They also refuse to say whether it will or will not void your warranty in the video. Instead they say "go look at your manual".

The price of the module is currently $477. They claim it will improve gas mileage from 10%-20% which is only 1.3-2.6 MPGs using his figure in the video of 13-14 mpgs (which is about what I get in-town). I used CarMax website (https://www.carmax.com/research/mpg-calculator) to calculate fuel savings on 15,000 miles per year. I input $1.95 (the current cost of diesel where I'm at), the standard 15,000 miles per year, 14 MPGs on car1, and 17 MPGs on car2 (being generous even though it is only 2.6 mpg increase). It says I would save $369 per year driving 15,000 miles per year if I had a 20% increase in fuel mileage (the max they say I can save). At 10% increase (14mpg and 16mpg being generous again) it's only $261.

What does all this mean? It means I'd have to use their product for 1.5 to 2 years before it would pay for itself. Not a deal IMHO.

 

To me it seems like the original edge juice for the 6.0 which wasnt that great if you look back at it. I have a hard time wanting to put a device that simply misdirects the factory tuning by altering values. I think flash tuning is far more reliable. I also dont think we will be seeing super great mpg out of these heavy trucks at the power levels and highway speeds we have. I think it would be nice but i imagine altering driving habits would yeild the same goals cheaper then the module

 

Yes, agreed on this one. Also the luck of not hitting stoplights.

 

I read about them a few months back and the claims were great but also walked back with something to the tune of changing driving habits to get the gains. I have seen giys on facebook sing praises of this module but i also assume most folks lie about fuel mpg or dont actually properly track it. I dont properly track my fuel numbers. I do check the numbers everyonce in a while though. Ive been unimpressed with my 2016 6.7 fuel mpg vs my 2006 f250. I hoped it would he substantially better but its not and most of the time its the same or worse. Now my 6.0 was race tuned and had a few other things done as well as mudtires and heavy bumper replacements but i assumed with the difference in the injection system it would be better. I do think if deleted my mpg would improve due to the lack of regens since i primarily drive intown and constantly go thru regens untill i drive on a short toad trip. Iirc the regens use 2-3g of fuel each time
