    Bully Dog


    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. In early 2014, Bully Dog and SCT merged. From the merger, we established Derive Systems to combine the market leading technologies and resources of the SCT and Bully Dog brands in order to offer our customers an unparalleled software solution to improve vehicle performance and the overall driving experience. The SCT and Bully Dog brands will continue to be used in the market, with the added benefit that both brands are now able to leverage the power of Derive to offer customers unmatched tuning solutions with the greatest number of features across the widest range of vehicles in the market.
