A plug-in tuner that adjusts fuel and boost through the engine computer to add power, bundled with the iDash 1.8 SuperGauge display for watching boost and exhaust temperature live. Banks splits the added power across six selectable levels so you can dial in how much you want.
why this one — This is the newer-truck version of the Derringer and it claims meaningfully more than the 2014-2018 kit, +57 hp and +73 lb-ft against +40 and +63, because the third-gen EcoDiesel has more headroom to work with. Six levels also means you can run it mild while towing and turn it up when you are empty. Same caveats as its older sibling: the numbers are Banks' own, and while Banks calls it 50-state compliant there is no CARB Executive Order number on the page, so we make no street-legal claim here.
CLAIMED (manufacturer) - bankspower.com product page states "+57 hp and +73 lb-ft torque" at Level 6, plus "1 second faster 0-60" and roughly 10 hp per level across 6 levels. Banks' own figures, no independent verification found this pass.
