Street Tune Only PowerStroke 6.7L F250-F350 (2015-2016)

Custom Tuning for Duramax diesel engines, providing increased horsepower and torque, improved pedal response, and optimized engine efficiency. Unlike handheld programmers, custom tuning from Calibrated Power (Duramax Tuner's parent company) re-calibrates the ECM (engine control module) to run the engine more efficiently and produce more power. This complete tuning package typically includes custom tune files, HP Tuners credits, an HP Tuners RTD4 Flash Tool, and an ECM bench unlock service. Specific gains and features vary by vehicle application (e.g., up to +110HP and +330 ft-lbs for a Sport Tune on a 2024-2026 L5P Duramax).
