Bully Dog was formed in 1998 in Aberdeen, Idaho. The founders of Bully Dog Michael, Phillip, and Daryl Klassen --were heavily influenced by their father Harold's interest in improving vehicle performance. Several years prior to the company's inception, Harold had experimented with increasing performance on his diesel farm tractor by injecting propane into the engine's combustion chamber. In 1998, Bully Dog's owners took this concept and developed and patented a safe and effective propane injection system to enhance diesel engine performance. These systems were first sold out of their farm shop, but as demand increased, the owners moved the company to another location and officially organized Bully Dog. Bully Dog's quest was now to be recognized as the leader in the diesel performance industry, which motivated us to stay abreast of new technology in this industry. With the introduction of electronic components and software to improve performance, we began to research new types of products like intake and exhaust systems to complement our electronic components. Bully Dog was now able to offer a complete performance package. In 2005, the company expanded its range of products to include performance products for gasoline powered vehicles.

Each Bully Dog product is built to ensure that it consistently meets and exceeds expectations, yours and ours. Each product goes through an in-depth research and development process (R&D) followed by a grueling development procedure that is carried out by a staff of the best engineers in the world.

Product innovation is key and Bully Dog takes innovation very seriously.

Then in 2008 with the Triple Dog Gauge Tuner, we were able to combine a vehicle engine tuner, monitor, gauge and diagnostic device all in a single unit. The GT monitors and displays over fifteen different vehicle parameters (PIDs) and it includes our all new Driving Coach feature which teaches end users to maximize their vehicles fuel economy potential. The GT performs vehicle diagnostics by reading and erasing diagnostic trouble codes; this level of vehicle transparency isn't offered by any OEM or by any ot her aftermarket product. Also included is our performance testing feature designed to test a vehicles' performance capability on the drag strip; couple this with our free PC analysis software and users can also determine vehicle horsepower. The GT does it all and it works on the largest range of gasoline powered vehicles; in fact the GT works on eight different vehicle makes and over 50 different models. The WatchDog was introduced in 2009 and works on all 1996 and later vehicles with an OBDII port common to North America. The WatchDog serves as a digital gauge/monitor and features a valuable Driving Coach for gas and diesel powered vehicles. It features the ability to monitor over 20 vehicle parameters all while you receive valuable driving suggestions from the Driving Coach to maximize fuel economy.
