  Propane Injection Systems by Bully Dog

  Bully Dog Technologies has developed the premier system that increases horsepower, torque, and diesel mileage! 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. By fumigating the intake air with propane, there are dramatic increases in power, torque and diesel mileage. By using a dual stage regulator and drawing vapor from the tank, this system creates one of the most user-friendly, maintenance-free systems available. Exhaust temperatures are only slightly increased or, in many cases, decreased. This system can be adapted to any turbocharged diesel and is easily transferred from vehicle to vehicle.

  Transmission Shift Kit

  These Bully Dog transmission kits increase line pressure in the transmission, which reduces torque converter and transmission clutch slippage and improves shifting. They are easy to install using basic hand tools. Bully Dog’s shift enhancers improve shift and line pressure while reducing slipping and lowering heat. The end result is firmer, quicker shifts, which vastly improves the driving experience and longevity of the transmission by lowering transmission temperatures.
