I am new to the diesel community. I bought my truck 6 months ago. Its a Dodge Ram 4x4 with the 6.7 cummins. I would like to know if anybody could tell me about programmers that can increase the fuel mileage? And any other modification that would help. Also How much will this improve the fuel mileage?

 

Any programmer that will let you remove the dpf and the egr will help mileage and reliability significantly. Reports of 4-5 mpg increase with deletes is not uncommon.

Smarty from Mads
Black Maxx and XRT from H&S
Edge has a new version of their juice and attitude out also.

All of those will let you do the deletes, and give you more power if you want it. You'll have to check your build date on the truck though, the programmers won't work on ones built after a certain date, but I believe Edge's box will.

 

he is good being its a 08. smarty, xrt and black max will work. edge race will work but it dont do the same as the others

 

My truck is an 08 and recently got about 12-13 mpg in town! That's ridiculously less than any other cummins I've owned. However, if I spend the $1200 to $1500 to install a programmer, EGR delete, and DPF delete I may increase my mileage by 5-8 mpg. If I get a new truck every two years it just wouldn't pay...the money I would have spent to delete everything buys a lot of fuel in 2 years! Plus, it deletes any warranty! So, if I spend the money to delete everything (including the warranty) to increase my mileage and my motor goes out (god forbid) then it costs me even more.

I'm not looking to void my warranty...just improve performance and fuel mileage. My question is this: Can just a programmer, cold air intake, and DPF back performance exhaust do the trick without voiding the warranty? I've done this with all of my trucks, with the exception of removing the chip for any service jobs. This also affords me the opportunity to take everything off upon the sale of my truck so I can either apply it to my next truck or sell it used and get some (most) of my money back. For example: I bought a superchip for my 5.9 for less than $300 and sold it 3 years later for $220. I also sold my cold air intake for 2/3 the cost of new, so all and all it didn't cost me much to increase performance and fuel economy.

Anyone?

 

the dpf is what is killin your mpgs

 

If I delete the dpf then it voids any warranty and I would be out on a limb if anything should happen. Is there a way to delete the dpf and not have the dealership know about it?

 

I helped a friend of mine install a pipe with a flange on it to delete the DPF assembly on an 08 6.7 cab & chassis 5500 with an 11' service body on it and we put the H&S XRT tuner in it and are doing all modifications for mileage going to stick with the stock muffler being as it flows straight through and the dpf is what is causing virtually all restrictions in the stock exhaust so as I find out more about his mileage results i will know more about how much the dpf really does hinder performance and fuel economy and it has the Aisin 6 speed auto in rather than the 68RE or whatever is in the smaller vehicles

 

bobcat67, does this delete the dpf without actually removing it or do you have to remove the dpf section of pipe?

 

you have to remove it

 

isn't there some guys drilling it out and still leaving on the truck. it looks stock but still picks up the milage. i don't want some nosie DOT inspector looking under my truck and putting me out of service. but i need to do something to get my milage up. its killing me over the road. the best i have done is 15mpg on flat roads doing 65.
