Stops the competition dead in their tracks. Results in torque and power gains across the full operating rpm range, starting right off idle and marching to the shift point in each gear. Derringer is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFR, Knock, and coolant temperature, just like your engine's ECM. Its microprocessor-based electronics are able to actively and safely optimize calibrations in real-time. No competitive product does that.
Derringer has six switched settings. Level 6 produces the Best in Class performance and knocks you back in your seat. The Level 3 setting is for work use and has a great mid-range feel. When running Level 3 with a loaded work truck and/or pulling a trailer, your on-ramp merging speeds and passing times are greatly improved.
The electronics are enclosed in a compact housing which is easily concealed and communicates using B-Bus (Banks Bus) with other devices such as our iDash 1.8 DataMonster or iDash 1.8 SuperGauge. The Derringer connects in line with your truck's engine sensors. But, unlike others, it also connects to the vehicle's OBDII diagnostic bus connector. A CAN (Controller Area Network) transceiver chip communicates with OBDII or B-Bus, allowing our microprocessor to talk with the vehicle.
Health Monitoring: We monitor the health of Derringer 100 times a second. If the health monitoring system reveals any malfunction, the Derringer instantly bypasses itself, sets a device diagnostic code, and returns you 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 a Derringer - you just choose your setting.

The Derringer tuner — When it comes down to it, you want a real 6.7L Power Stroke tuner. You want something that makes big power and doesn’t kill your truck. After all, you just spent a lot of money on that beast. The Banks Derringer 6.7L tuner is the only option you should be plugging into your truck. Look, the other guys claim big numbers and we call bulls—t! We tested every other tuner on the same dyno, same day, same weather conditions, with the same technician… Same damn test, period! There’s only so much you can do by just intercepting the fuel rail pressure sensor. That’s where all the others fall short. The Derringer is the only tuner that actually utilizes your truck’s ECM to make intelligent calculations!
After months of testing, the results are in and we can’t wait to share them.
Check out the data below followed by the jaw-dropping list of features.
NOTE: Dr. Performance and Stealth both use the same box.
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.
How the Derringer does what it does, and why.
There’s no easy way to make more power your daily driven 6.7L Power Stroke with Ford’s ECM and factory turbo, no magic flash, or special “chip” available. We had to go the tuner route, and making an inline tuner for your truck was no easy task. We have almost a thousand man-hours into Derringer development. Fortunately, we’ve been making tuners for 20 years, so we know what we’re doing.
The Derringer is a plug-and-play microcomputer designed for easy installation, it’s enclosed in a compact housing which is easily concealed, and connects to the iDash 1.8 SuperGauge for the ultimate in information and power selection, unlocking three additional power levels.
AutoRate®
Unlike the fixed tuning used by others, the Derringer calibration is continuously adjusting to provide you the peak possible 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.
TransCommand® Active Transmission Safety System
In addition to AutoRate Adaptive Tuning, the Derringer utilizes key engine and transmission parameters to enhance shift performance and improve the longevity of your transmission. Because the competitors lack the essential OBD-II data, they always add power at wide-open throttle—no matter what! This can cause excessive transmission slip, torque converter clutch slip, and even 170 HP engine derates in order for the transmission to complete the shift. This harms the overall performance and degrades your transmission. The Derringer is meticulously calibrated and extensively tested to properly modulate power during shifting, optimizing performance and safety.
ActiveSafety®
The Derringer is the only tuner on the market to include ‘Active Safety’, an active failsafe system that utilizes bypass relays to smoothly transition your vehicle to stock power levels in the event of any trouble signs in the Derringer. The system constantly monitors various parameters over 50 times a second to ensure that everything is operating as it should. If any competitive tuners lose power or fail in any way, they will instantly trigger a “limp home” mode where all power is lost and the vehicle dangerously slows to a crawl. If the same fault condition occurs to the Derringer it will gracefully remove its additional power and return to stock power levels without a hitch.
Additional Features
The Derringer for 6.7L Power Stroke is the most sophisticated inline tuner available. We hope you have as much fun driving with it as we did making it.
