Bully Dog Technologies' Triple Dog GT downloader is specifically for 2009 Dodge 2500 to 4500 model trucks powered by a 6.7-liter Cummins diesel engine. The device is actually four products all rolled into one: a downloader for adding power; a tuner allowing for multiple drivetrain settings to be tuned and adjusted; a gauge that is fully customizable to each user's preferences that monitors four gauge functions at one time; and a "driving coach" - software that monitors wasted vehicle energy and informs the driver how to change driving habits to increase fuel economy.
