Description
Already own an iDash? This is the Derringer HO module by itself — same +117 hp / +225 lb-ft you'd get from the bundled kit, just without the iDash display. Plug it in, link it to your existing iDash Pro or Data Pro, and pick from six power levels on-the-fly.
The Derringer High Output for the 2020-2022 L5P Duramax takes the truck from 419 hp / 835 lb-ft up to 523 hp / 1,039 lb-ft — without a reflash, without a trace in the ECM, and without compromising your factory warranty.
