I have one of the bully dog ones for my 01 ram couldn't tell a bit of difference total waste of money lucky I didn't pay for mine it came with the truck lol

If you have the right Bully Dog with the right tune, they made a world of a difference. Unfortunately, they got busted along with Pittsburg Power and now they are DEF friendly JUNK!!! The way it was, you got deleted and set up with a Bully Dog tuner and made BIG power. I am quite familiar with diesel power.
