Do any of these add fuel mileage and which ones? Do you have to have them on the low settings to get the fuel mileage increase?or on the higher settings? What if you left it on higher settings but just drove casually? Can you do this or is it too hard on everything still? (what i mean is if I left a programmer on high settings and my wife uses truck sometimes to drive acrooss town to work will it still be hard on engine on high setting)? or what are the consequences?

I have the bully dog with outlook moniter and it show all the poramitors needed to run safe with the ability to move it from truck to truck is a great deal to (via internet download)you can also change speedo and download more power it has endless options and they are always making it better and you do not have to buy a new one you just hook it up to your computer.Bully dog is the only opption for me!

 

Just posing a question?? If you were you CEO/president/owner of Cummins and you kept replacing engines because of aftermarket chip/programmers and it was coasting you a great deal of money to replace would you develop procedures to determine when a chip/programmer was used to determine if that was the cause of the engine failure?? Or would you just keep replacing engines??

 

Still no response to my question above????

 

that development cost may exceed the costs of replacing motors. I have not heard of too many motors getting swapped out because of a chip or programmer.
