Bully Dog was formed in 1998 in Aberdeen, Idaho. The founders of Bully Dog â?? Michael, Phillip, and Daryl Klassen were heavily influenced by their father Haroldâ??s interest in improving vehicle performance. Several years prior to the companyâ??s inception, Harold had experimented with increasing performance on his diesel farm tractor by injecting propane into the engineâ??s combustion chamber. 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. Bully Dog products have you covered with increased performance, added safety and improved economy. This is evident with the Triple Dog Downloader, Outlook Monitor and the new Performance Management Tool. These products offer the safety of a module married to the performance and flexibility of a downloader. Product innovation is key and Bully Dog takes innovation very seriously. In the past 8 years, Bully Dog has been first to market with product fitment and function over 80 times. They are the ONLY manufacturer that allows you to take their product for a free test drive with the Tri Before You Buy program. And in 2005 with the release of the Triple Dog Downloader and Outlook Monitor, Bully Dog revolutionized the market with the ability to adjust power, safety and economy levels on-the-fly while driving down the road. So what are you waiting for, find the right product for your vehicle and Unleash the Power!
