Chipping Your 6.7litre Dodge Ram

I did this with a predator diablo tuner I called the numbers for the various manufactures that I located on the internet and talked to a person that his shop only works on these type diesels I now live in georgia he is in north las vegas he even rebuilds and furnishes advise to the military the hummers have a duramax since they first came out. tuning the duramax does not help as much because the extra power is lost in the allison tranny the dodge gets the most out of this according to him on the economy mode I get forty extra horse power and eight too nine miles to the gallon better mileage when you take your truck into dodge be sure and put the stock tuning back if there is a upgrade and dodge changes the computer in your truck your tuner then will not work and the predator is one of the few that does not leave a imprint on your computer in your truck, that means dodge will never know you changed anything it helped me but to each his own
