    1. GREAT Power addition, haven't seen mpg increase yet! Review by JJJMXZ
      Overall Quality
      Ease Of Installation

      Installed on my stock 2007 Dodge Ram 2500 4x4 6.7L Cummins Diesel and LOVE it! Engine seems much more smooth throughout the powerband in the economy/tow mode, unbelievable power in the performance mode and haven't yet had it in extreme mode. Installation and computer updates are simple and the screen options are best on the market!!!! Haven't seen an increase in mpg yet, but I think it is because I am now ALWAYS on the throttle to feel the sweet power!!

      The options on the Bully Dog are amazing. For example, the dodge headlights suck at night and I have asked the dealer since truck was new if they could set it up to have the high beams and fog lamps on together since their lights are the worst on the market, been told its NOT possible. Bully dog does it with the touch of a button!!!!! (Posted on 8/25/11)

    2. GREAT RESULTS! Review by Aldon Lewis
      Ease Of Installation
      Overall Quality

      So, in all my years of owning a Ford Powerstroke diesel, I never thought you could make a great truck better. I finally took the leap of faith, and decided to use a Bully Dog tuner in the truck because I've heard great reviews in the past.
      I honestly have to say, there was nothing short of perfection when it came to my whole experience with the Bully Dog GT. The screen is easy to read, it’s easy to use, and the install took me less than 1 hour from start to finish. Being that my truck is completely stock (no turbo back exhaust, no air intake) I was pleasantly surprised that I got an extra 3-4 MPG out of this thing! Good job Bully Dog!
      I plan on getting these Triple Dog GT's for my workers trucks too which are all Dodge Cummins 5.9 Diesels and hope to have the same results.
