A Tuner Above The Rest

The Derringer is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFP, knock, coolant temperature, and EGT, just like your engine's ECM.

It actively and safely optimizes calibrations in real-time thanks to its OBD-II connectivity while providing huge performance gains, all while keeping your factory ECM happy, temperatures under control, and transmission safe.

No competitive tuner does that.

Horsepower Gains

Banks vs The Rest

The other guys claim big numbers on paper but simply don't deliver in the real world! We tested every other tuner on the same dyno, same day, same weather, and same technician. All they do is add fuel with no aditional air.

That’s where all the others fall short, infact power can even be reduced under load as the tuner box and factory ECM fight each other over rising Exhaust Temps and unsafe power delivery.

 

Torque Gains

Test Vehicle Used: 2017 Chevrolet Silverado 3500 Dually 6.6L Duramax L5P. Factory intake and exhaust. All tests run on the same truck, same day, same conditions. Tested on Mustang DYNO, 10-second sweep

 

Get What You Pay For

Dont waste your money on competitive products offering cheap thrills that only dump fuel into the engine with no added air.

Invest in quality backed by engineering. When you compare the power gains per dollar spent, there is no question who offers the highest smile per dollar ratio.

 

Consistent Power Delivery

The real-world benefits of powerful tuning done safely and reliably really show when you’re hauling a heavy load.

You do not want a cheap tuner that only adds fuel to the engine with no added air. That is just a one-way ticket to soot and high EGTs on your engine.
