I first got the bully dog programmer, but the next day got a email from auto anything telling me about the new release of the edge for my 2015 denial 2500hd, customer service was super cool and let me return it without a restocking fee, and got the edge, so far I'm getting almost 4 more miles to the gallon on the highway, and in sport mode it rips, it has so much torch and u can feel the added horsepower, after I break in my truck I can't wait to get on the accelerator some more,def worth the $!
Edge CS Programmer
I have had my programmer for about 3 weeks now and like it. I have only had it in trans only mode so far to increase my mpg seeing how all I drive is highway. I have gotten just over 2 mpg better and that was with hauling a bunch of stuff in the bed. I didn't like that you have to remove a fuse to change modes, not sure if that was just to program it or if you have to do that every time you change modes. overall a good product and would recommend to anyone.
