One vehicle at a time

Reviewed By nathan s (MILLS, WY) Reviewed for a 2014 GMC Sierra —9/19/2015 5:38 AM

This is an awesome product. Installed right away and had a very noticeable difference just on my stock 6.2l gmc. I don't have anything modified yet but this still gave it bigger balls. The only bad part is even with the expensive price, you can only install on one vehicle at a time. You have to restore factory tune on last vehicle before new vehicle is set

Reviewed By Tom R (West Chester, PA) Reviewed for a 2015 GMC Sierra —8/4/2015 6:34 PM

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 $!
