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.

Bully Dog products are developed with you in mind and each of you has a different need, want and desire. Our products, all the way back to the first propane kits, reflect that. Bully Dog products are built to be flexible, allowing each user to get their own desired result, from outrageous performance on the race track to improved fuel economy driving down the highway.

Product innovation is key and Bully Dog takes innovation very seriously. In the past 12 years, Bully Dog has been first to market with vehicle-specific products and applications over 100 times while also being awarded many awards for our revolutionary products.
