Browse Duramax Derringer Tuners, Six-Gun Diesel Tuners, EconoMind Diesel Tuners, and more. Choose your preferred power level and enjoy your ride all while controlling temperatures and keeping your transmission safe.

Calibrated to safely give you the full power potential of your work or sport Duramax truck without soot, Banks Power’s emissions-compliant tuners and programmers offer built-in ActiveSafety® and AutoRate® to safeguard your powertrain. This active fail-safe system utilizes bypass relays to smoothly transition your Duramax to stock power levels should any signs of trouble appear in the Derringer. Additionally, unlike the fixed tuning used in competitors’ products, the Derringer continuously adjusts its calibration to provide peak performance in any driving condition.
