An inline tuning module plugs into your engines wiring between the factory sensors and the ECU, adjusting signals on the fly to change performance - unlike a full tuner it does not flash or replace your engine computers software.
why this one — Built specifically for the PowerBoost hybrid drivetrain rather than a generic EcoBoost tune force-fit onto the hybrid, so it accounts for the electric motor and battery system alongside the gas engine.
MANUFACTURER CLAIM: STILLEN's own product page states before/after wheel-dyno numbers from their own test truck; not an independent/third-party dyno. Also claims up to 15% fuel economy improvement in Eco mode, results-vary disclaimer included. Checked 2026-07-12.
