The Derringer tuner & i-Dash Super Guage Combo — 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 ECU to make intelligent calculations! Emissions Compliant: In Process
The truth is in the testing!
