I have a triple dog Bullydog system on my 05 chevy truck, I dont really pull anything and I never change the settings unless I am racing someone, would it help my fuel millage if I took it off or no?

I don't run Bully Dog, but I would have to say that you will get better fuel millage with it on. I believe that it will advance your timming there for make it more efficient. I might now have the correct answer for you but someone will very soon.

P.S that is a sick looking truck you have.

Thanks man, I getting ride of the 22's if u know anybody looking let me know. I love my DMax, wish I would have got one a long time ago. I have had it for almost a year now.

georgiaboy,

I have been reading this site for awhile, figured I better start posting...

My duramax went from about 14 to 18mpg (highway) adding the Bullydog tripledog with no other modifications. I had the same experience with my '04 Ferd powersmoke. It went from about 15 to around 18/19 mpg (hwy). It just seems like the trucks don't work as hard when they are programmed.

You could probably just set the programmer to stock setting and recheck your mileage.

PS: Very nice truck!:cool2:

i get better mpg with mine on crazy larry
