Derringer Tuner

Derringer has 6 levels, adjustable on-the-fly using the iDash.

Level 3 is designed for work use and has a great mid-range feel. When running Level 3 with a loaded truck and/or pulling a trailer, your on-ramp merging speeds and passing times greatly improve.

Level 6 produces best-in-class performance and passing power when you need it most, with a huge gain of 57 extra horses and 73 additional lb/ft of torque.

ActiveSafety^® health monitoring circuitry keeps an eye on the vehicle and the module itself 100 times a second.

If an issue is detected, the Derringer instantly bypasses itself, sets a device diagnostic code, and seamlessly returns the truck to stock power.

The Derringer auto-adjusts power if knock occurs due to bad fuel, and advanced coolant temp monitoring prevents power addition when the engine is too cold or overheated, preventing damage.

Maximum safe power is all automatic with a Derringer — you just choose your preferred power level and enjoy the ride.

The Derringer is the only tuner that utilizes your truck's ECM to make intelligent calculations. Utilizing the power of OBD-II, the tuner intelligently fine-tunes its calibration on the fly without you having to change its power level. The Derringer calibration continuously adjusts to provide peak performance under every driving condition.

The other guys claim big numbers on paper but simply don't deliver in the real world under steady-state conditions! We tested every other tuner on the same dyno, same day, same weather conditions, and with the same technician.

• Exhaust Gas Temperature (EGT) — Monitors EGT and intelligently modulates fueling to maintain a safe maximum EGT, protecting your turbo and engine.

• Altitude compensation — Senses ambient air pressure, controlling the turbocharger to maintain added boost and power as altitude increases.

• Diesel Particulate Filter (DPF) Regen — Monitors your DPF regen status to ensure the process completes successfully.

• Accelerator Pedal Monitoring — Rolls in additional power progressively, optimizing for both part-throttle fuel economy and max power when you ask for it.

• Full Power Timer — Allows for 30 seconds of wide-open throttle before transitioning to the recommended power level for sustained tow/haul.

• Intelligent Shift Tuning — Shift signal is optimized for the power level protecting the transmission, increasing shift speed, and avoiding ECM power derates.

• Tuned Hydraulic Pressure —Ramps hydraulic pressure faster than stock, maintaining engagement as power is added safely within factory limits.

• Torque Converter Clutch (TCC) Monitoring —Adjusts TCC slip to safe levels, lowering fluid temperature, and preventing extended wear.

• Calibration is tuned for optimum traction and performance providing the right firmness of shift automatically.

• Transmission Slip Monitoring - Light throttle shifts remain smooth and firm, full-throttle shifts are solid and decisive.

• This reduction in slip time also improves acceleration performance, an added benefit!

The Derringer is the only tuner available that includes Active Safety® health monitoring circuitry.

• Internal diagnostics check system 100 times per second.

• Checks MAP and FRP signals and monitors CPU activity

• Activates in event of failure or loss of 12V power
Bypass relays smoothly return stock power with no loss of power or "Limp Home" Mode.
