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.
Retailer copy attributed to SCT is unquantified - "Increase the power and performance of your stock 5.0L Coyote powered F-150" and "even a bone stock, unmodified F-150 will see noticeable gains in horsepower, torque, and fuel economy". SCT's own X4 page (sctflash.com/x4-power-flash-programmer) returned 404 on 2026-07-26, so the manufacturer side is unverified.
