Carefully applying science and engineering to our line of tuning products grants you safe and consistent power delivery every time. Our experts spent hundreds of man-hours developing the unstoppable Derringer tuner to create the only tuner that utilizes your Jeep’s engine control module (ECM) to make intelligent calculations. 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 Jeep 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 Jeep 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.
