Bully Dog Big Rig Caterpillar 3406B Performance Bundle – GT Tuner, VGT Turbo with Actuator #56154 & FTP Manifold #85500

Built for Caterpillar 3406B applications from 1989, this Bully Dog Big Rig Performance Bundle brings together three complementary components in one package. The Bully Dog Heavy Duty GT, VGT Turbo with Actuator, and ceramic-coated FTP exhaust manifold are selected to support stronger airflow, responsive performance, and dependable operation in demanding commercial use.

The Bully Dog Heavy Duty GT combines engine-specific preloaded tuning with in-cab monitoring. It offers settings aimed at power, economy, or a balance of both, while its gauges and customizable alerts help the driver keep an eye on important operating conditions.

The VGT Turbo with Actuator is engineered to provide reliable boost and improved airflow. Its performance-focused design can help reduce turbo lag, support horsepower and torque, and manage engine temperatures more effectively when the truck is working under load.

The ceramic-coated FTP exhaust manifold uses a durable, single-piece design to improve exhaust flow and help control heat. Thicker flanges and walls are designed to resist cracking, warping, and leaking, while improved flow supports quicker turbo response and long-term reliability.

• Bully Dog Heavy Duty GT – Part #46500
