2007 cummins 6.7 programmer
 

Looking to increase fuel mileage, don't care about hp gain. Anyone get a programmer? Results?

I just removed a H&S. 08 F-450 6.4. I did a dpf delete and ran the no HP gain with the lowest smoke setting. It smoked way too much, did not improve economy and the trans program was really harsh and inconsistant. I would not recommend it in a work truck. The 1999 cummins in my motorhome has a banks kit at 425 hp and does not smoke at all!

Get ahold of James @ rollin smoke diesel, H&S products work great have done many 6.4 s and my own dodge 6.7 and doing another as we speak , great customer service !!

You will also need to turn off the 4th injecter Cycle and set the EGR too like "0" .

H&S XRT or mini max will take care of all of that .

theirs other ways around it..

LOL a cummins expert I see !

Unloaded I get 19.998 mpg in my 6.7 with a H&S.

Good deal , is that a srw or drw , my mega cab dually I have hit 19 with it once otherwise usually 16 18 empty .
