Derringer is the BEST Ford 6.7L inline tuner. Here's why.

The Derringer is the most advanced inline tuner available for the 2011-2019 Ford 6.7L Super Duty, not only delivering un-matched horsepower and torque but it's the only tuner that communicates with your truck's computer. Years in the making, the Derringer is jam-packed with features that will keep your diesel-powered Super Duty safe while delivering the power you need.

Gale Banks explains how Derringer differs from all other inline tuners, especially the ones sold by county fair snake oil salesmen.
