Looking for some info, have a 2004 2500hd with a 6.0. Am thinkng of putting a chip in, they advertise 3-6 more MPG and 50 HP more. Do they really make much of a difference? Pull a 5th wheel camper and could use some extra MPGs. Thanks

 

im not sure what it will do for 6.0 but i but the super chip flashpaq on my 04 4.8 and it maid no difference on anything

 

I have a 01 5.3 and i put the bully dog power pup on it and it made a pretty big difference

 

I have heard that most chips out there do not do much of anything. I have read on another forum that a Black Bear custom tune is the best mod they have ever done. Far better than any off the shelf programmer. I have no personal experience with it though.

 

X2 for waht MDTAHOE said. I'm getting a Blackbear soon. But for the money, a blackbear tune seems worth it, costs less then many programmers.

 

yalp. go get yerself a baer tune. its a custom tune and you can have them do anything. turn the rear o2 sensors off. whatever. cheaper and uber leet better than any potato chip. plus warranty and other stuff too.
