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.
Derringer has 6 levels, adjustable on-the-fly using the iDash. Level 6 produces best-in-class performance. 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 are greatly improved.
ActiveSafety health monitoring circuitry keeps an eye on the vehicle and the module itself. It checks its health 250 times a second. If it detects an issue, Derringer instantly bypasses itself, sets a device diagnostic code, and seamlessly returns the truck to stock power. Plus, Derringer's special coolant temp monitoring prevents power addition when the engine is too cold or overheated. The Derringer also auto-adjusts power if knock occurs due to bad fuel. Maximum safe power is all automatic with Derringer - just choose your preferred power level and enjoy the ride.
The Derringer tuner is the only option you should be plugging into your truck. 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 conditions, and with the same technician. There’s only so much you can do by just intercepting the fuel rail pressure sensor. 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. The Derringer is the only tuner that actually utilizes your truck’s ECM to make intelligent calculations. Hundreds of man-hours went into Derringer's development and the results are nothing short of impressive.
Test Vehicle: 2019 Ford 6.7L Power Stroke F-250. Factory intake and exhaust. All tests run on the same truck, same day, same conditions.
Tested on Mustang DYNO, 19-second sweep.
Dont waste your money on competitive products offering cheap thrills, 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.
The real world benefits of powerful tuning done safely and reliably really show when youre hauling a heavy load. In the case of TSPerformance, EGTs got hot so fast we actually saw the engine limit its power output before we could complete our real world tow test!
The Derringer calibration is continuously adjusting to provide peak performance under every driving condition. By utilizing the power of the OBD-II data, the tuner intelligently fine-tunes its calibration on the fly without you having to change its power level.
The Derringer is calibrated to modulate power during shifting while ramping up hydraulic pressure for better engagement. Competitors lack OBD-II data and always add power at wide-open throttle causing excessive transmission, clutch, and torque converter slip.
The Derringer is the only tuner available that includes Active Safety® health monitoring circuitry.
