Bully Dog is a frontrunner in performance ECU calibration technology for gas and diesel vehicles. Its calibration software platform adjusts key performance parameters to better respond to the unique demands of vehicles, whether it's adjusting for tire size, axle lockers, throttle sensitivity or shift firmness. The brand's advanced handheld programmers offer easy installation and quick access to better performance, added safety, and improved fuel economy.

Custom tuners are also required to adhere to the guidelines of the Clean Air Act when developing their own tunes for Bully Dog's devices. The brand continues to innovate and develop new products to meet its customers' needs and help them achieve the desired performance from their vehicles.
