Bully Dog Technologies' complete history is built around the diesel engine. They were the first company to develop and patent a safe propane system for the diesel engine. They first developed the propane injection system for their own tractors and then their own pickup trucks before sending them to market. In the fall of 2002, they were first to the market with a plug-on module called the Torque Dog and in 2004 a downloader called the Power Pup for the Dodge Cummins diesel. In 2003, they introduced the Power hound module for the 6.0 Liter Ford Power Stroke. Their engineers concentrate on modifications that will increase horsepower, fuel economy and torque. Bully Dog is staffed with a highly professional team that knows diesel performance and will strive to provide you, the customer, with the most functional performance modules on the market. Their customers can be assured that they are at the head of the pack in diesel performance!

Bully Dog is the leader in diesel nitrous technology. The Bully Kicker kit gives up to 150 hp. The Dual Shot Bully Kicker kit gives up to a 200 hp shot, complete with throttle switches, a pressure switch and high performance solenoids. The Dual Shot Racing kit blows away the competition with a huge gain of up to 250 hp. All nitrous kits are dry kits. Nitrous injection must be matched with diesel fuel input to show proper gains.

When propane is used properly, it will keep your engine cleaner with less carbon buildup and cleaner oil. Propane is a high-octane fuel and burns slower and longer therefore, propane will help diesel burn more thoroughly, increasing power and torque. With propane your engine should last longer, get better fuel economy and have significantly more power.
