A handheld device that plugs into your truck's diagnostic port and loads a new engine tune -- either one of SCT's pre-loaded calibrations or a custom file from an SCT-authorized tuning shop. It also works as a gauge display and can read/clear check-engine codes.
why this one — SCT's own X4 programmer line, officially announced by SCT as supported for the 2021-2023 F-150 5.0L Coyote (bundle part 7015PG-B, includes tuner + custom ECM cable), with pre-loaded tunes for 2021-2022 and 2023 plus custom-tuning-dealer support. This is a distinct product from the Bully Dog BDX-branded SCT programmer already in this catalog. SCT has not published horsepower or torque numbers for this application, so no power gain is claimed here.
Gain shown is a no published number, not a guarantee. Price is a list price and can lag the retailer; confirm at checkout. See our affiliate disclosure.
