Bully Dog Triple Dog GT Tuner (49-State Legal) Reviews

2012 F150 5.0

Reviewed By Tim K (Monroeville, AL) Reviewed for a 2012 Ford F-150 —7/27/2014 5:31 PM

Installing the programmer was a breeze. After installing on my truck I could feel the increase in HP and when driving the truck properly the mpg picked back up above what I was getting with stock tires (running 13.5x35s now). I had a question the day after installing the programmer and called the help line and was impressed with the help I received. The only negative is the overall size of the GT head unit. Could be a bit larger for visual aid.
