Computer controls on our trucks are a love-hate relationship for some, especially new Hemi truck owners who's ECUs seemed to be programmed at Pentagon defense levels. For years we've been asking for tuners for Ram ½-ton and ¾-ton trucks but no one was able to crack the code—until now.

After perusing the information available on the many features available to Ram owners, we thought it best to see what all the fuss was about. Bully Dog was nice enough to show us the installation and dyno flogging necessary to quantify its claims on a 2012 Ram equipped with the 5.7L Hemi V-8. After seeing what went into the installation, we are quite confident in saying that anyone can add horsepower to their Hemi truck in a matter of minutes.
