6.7 Bully Dog Power Pup
The bully dog is awesome cant wait till they come out with the extreme setting, it got me 2-3 mpg and at todays diesel prices thats important. It was really easy to install took about 10-15 minutes I run it on performance most of the time ,but its hard to keep your foot out of it. I would buy it again
