Detroit DDEC IV/V Performance Bundle – GT Tuner, Stage 1 Turbo & Exhaust Manifold

Built for Detroit Diesel DDEC IV/V engines from 1999–2007, the Bully Dog Big Rig Detroit Performance Bundle combines three proven upgrades into one complete performance package. With the Heavy Duty GT, Detroit Stage 1 Big Rig Turbo, and ceramic-coated FTP exhaust manifold working together, this bundle is designed to help your truck pull harder, breathe better, and operate more efficiently.

At the heart of the package is the Bully Dog Heavy Duty GT, delivering optimized tuning options for power, economy, or a combination of both, with available gains of up to 75–100 horsepower. The GT also provides valuable monitoring and safety features, including customizable alerts for coolant temperature, oil temperature, boost, and vehicle speed.

The Detroit Stage 1 Big Rig Turbo is engineered to deliver reliable, consistent boost while improving airflow, reducing turbo lag, and increasing horsepower and torque. Better airflow can also help reduce engine temperatures and improve fuel efficiency.

Completing the package is the USA-made ceramic-coated FTP exhaust manifold. Its single-piece construction and improved exhaust flow are designed to reduce EGTs, lower underhood temperatures, improve turbo response, and support increased fuel economy and power. The manifold is also built with thicker flanges and walls to resist cracking, warping, and leaking, helping keep your truck on the road and out of the shop.
