actually no, i proved that you would lose money unless you lived to be significantly over 100 years old.

They will continue to refine the calibrations, and I think as a whole make some huge efficiency gains to the modern emissions systems. In the mean time I think it’s important for us to ask questions as they come up to understand where the data came from and how it’s being used.


All im saying is that if you get 1000 miles per gallon of DEF, and you're getting 20 mpg then your getting 50 gallons of diesel to 1 gallon of DEF.

If you're getting 23 MPG, and presumably an increase in efficiency produces a decrease in DEF consumption based on the statements made thus far, then you would burn 43 gallons of diesel. which would if linear equate to about .9 gallons of DEF over the same distance. so if you drive 15K a year, you will save 1.5 gallons of DEF a year maximum.

Now, lets say this tuning kit costs the absurdly low price of 500$ and a gallon of DEF costs about 3$. It would take you 160 gallons of DEF to equate to the cost of the tune, which at 1.5 gallons per year given 15K a year, would take you like 100 years to break even.

Im not ragging on there tunes, im just saying that that data is misleading at best. HP numbers, ok, torque numbers ok, MPG numbers ok, but trying to tell me that this tune will save me money on DEF is absurd.

. . . . . .

On those rare occasions when I had to use my truck as a back-up car, yes, I got around 18 - some stop-and-go-, mostly open road.

Most of the time I use the truck for towing - my "toys" (both the box trailer & boat trailer) each about 11,000 lbs. Average on long trips runs about 11 mpg.

That was before a strange animal crawled under my truck and bit off some funny-looking stuff...Ö.

As a side-note, .I like to base my mileage bragging rights by actual miles between fill-ups.

Attending a big car show in Las Vegas over the weekend - that's about 220 miles each way - all Interstate, but some of that ( I-40) involves considerable altitude changes. If anyone's interested in the difference between "bone stock" ( as in crippled by pollution devices that may actually do more harm, overall, to the environment than...well...ÖÖ) and now that some funny looking parts fell off...will report on my return late Sunday.

LML6600DMAX I just love how everyone is caught up on mpg driving a damn 8000lb truck around.

SilverGorillaLML 30mpg? Really? Maybe after resetting the dic, coasting downhill with another truck pushing you. My lml on stock fuel and air never saw over 20. Once the big single and fuel went on, maybe 16. This truck turned down to 800hp or so maybe gets 14 Honestly with these trucks anything around 18 is pretty good for their weight and aerodynamics.
