I am selling a new in the box Stealth Module for a 13-18 Ram with 6.7l Cummins. I bought this from Stealth in September 2019, then when the EPA went nuts I decided to jump and grabbed a tuner and rest of the mods. This module is a piggyback unit and leaves no footprint in case want more power and mileage and your worried about warranty issues. They get great reviews I'm looking for $450 https://www.stealthmodules.com/collections/ram/products/ram-cummins-6-7l-13-19
