The Derringer is an inline tuner. Rather than rewriting the truck computer, it plugs into the engine sensor connectors and adjusts fuelling in real time, which is why Banks calls it warranty-friendly and says it leaves no reflash footprint on the ECM.
why this one — Banks publishes separate dyno numbers for each model-year group instead of one headline figure across nine years, which is a more honest way to quote gains than most of this category manages. Two things to budget for before you order. Part number 66653 is the tuner on its own, and you need a Banks iDash gauge to select or change power levels, so the real out-the-door cost lands well above the $490 sticker. And Banks does not publish a CARB or 50-state statement for this part, so check your own state rules before fitting it to a road truck.
