Bully Dog

Bully Dog began in American Falls, Idaho in 1998 as an enthusiast business focused on improving diesel engine performance. What started as a family venture experimenting with propane injection systems has evolved into one of the most respected names in vehicle performance tuning. The brand has come to stand for leading-edge engine ECU calibration, high-quality aftermarket parts, and precision data-logging & monitoring technology.

Performance Tuning Technology

At the heart of Bully Dog's product lineup are their computer chip programmers, handheld devices that fundamentally change how your truck performs. These tuners connect directly to your vehicle's OBD-II port and upload custom calibrations that optimize engine parameters for increased horsepower, improved torque delivery, and enhanced fuel economy. Whether you're towing heavy loads, tackling off-road terrain, or simply want better daily performance, these programmers offer multiple power levels that can be switched on-demand to match your driving conditions.

Tunes that are preloaded in their devices have gone through hundreds of hours of testing to ensure the safety of the drivers and the environment overall. The brand's flagship tuners feature WiFi connectivity for cloud-based updates, touchscreen interfaces, and the ability to store multiple custom calibrations. Beyond simple power gains, these devices function as comprehensive monitoring tools, displaying real-time engine data including boost pressure, exhaust gas temperature, transmission temperature, and dozens of other critical parameters that help you understand exactly what's happening under the hood.

Professional Installation and Monitoring

To complement their tuning devices, Bully Dog offers a complete ecosystem of installation and monitoring accessories. Gauge pods provide a clean, professional mounting solution for displaying your tuner or additional gauges in the cabin. These pillar-mount and dash-mount options integrate seamlessly with various truck models, giving you constant visibility of critical engine data without cluttering your dashboard or obstructing your view.

For enthusiasts who want to expand their setup, the brand also produces computer chip programmer OBD blocks, input cables, and power cables that ensure reliable connectivity and proper power delivery to your tuning equipment. These accessories may seem minor, but they play crucial roles in maintaining consistent communication between your tuner and your vehicle's ECU, preventing interruptions during the tuning process that could potentially cause issues.

Applications Across the Truck Spectrum

Bully Dog offers tuners, turbos and manifolds built to take big rigs to the next level. The company's product range spans from light-duty pickup trucks to heavy-duty semi-trucks, supporting engines from Cummins, Powerstroke, Duramax, CAT, Detroit Diesel, and more. Bully Dog continues to produce innovative technologies that make use of advances in mobile computing, Wi-Fi & Bluetooth communication, cloud computing, and performance monitoring to deliver unparalleled performance. This commitment to staying at the forefront of automotive technology ensures that whether you drive a modern truck with advanced emissions systems or an older diesel workhorse, there's likely a Bully Dog solution engineered specifically for your application.
