opinions on Bully Dog programs
 

I am getting ready to take a trip with my camper in a couple weeks and was thinking about getting their free download to try on the trip. Buying a programer before hand is out of the question so this is my only option. I was also going to do a muffler and cat delete, is there any one that sells a replacement pipe for this?

get some 4 inch pipe put it in place of the muffler and cat i wouldnt use tunes till you have gauges. just be safe if you do try a tune see how much power it is i wouldnt go over 60hp if your towing

well i have the same truck. 04 3500. and i have the bulldog and i would recomend it. it greatly increases mpg and of course you dont have any problems with hauling but itll definently give your truck a huge boost

Yeah bullydog is pretty good. It's nice adjusting on the fly.
