Bully Dog Big Rig Detroit DDEC IV/V Performance Bundle – Detroit ECM Tuner, Stage 1 Big Rig Turbo #56900 & FTP Manifold #85301

Built for Detroit Diesel DDEC IV/V applications from 1999-2007, this Bully Dog Big Rig Performance Bundle brings together three complementary components in one package. The Bully Dog Heavy Duty Detroit ECM Tuner, Stage 1 Big Rig Turbo, 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 Detroit ECM Tuner provides engine-specific ECM tuning in a straightforward package for fleets and owner-operators focused on pulling power, drivability, and fuel-efficiency potential. This tuner is intended as a calibration tool and does not include an in-cab gauge display.

The Stage 1 Big Rig Turbo 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.
