24-26 GM 6.6L L5P Duramax Banks Power Derringer Tuner

Fits: 2024-2026 Gm 6.6L L5P Duramax (Requires Existing Idash Pro)

While specific listings for Banks Power 67137 Derringer Tuner aren’t always shown under that exact number, the **67137 SKU refers to the Banks Derringer High Output for the 2024-2026 GM 6.6L Duramax (L5P) when used with a compatible iDash Pro monitor. This inline tuner is designed to safely add power and torque without flashing your truck's ECM — meaning it is generally more warranty-friendly than traditional flash tunes. It plugs into the engine and OBD-11 network, communicating with your truck’s sensors in real time to optimize fueling, turbo boost, and other parameters.

• Transmission smart tuning: Reduces added power during gear shifts to protect the Allison transmission and smooth shifting.
• Plug-and-play: Connects inline with engine sensors and OBD-II for live tuning.
