A tuner is a handheld device that plugs into the truck's OBD2 diagnostic port and rewrites the engine computer's settings (fuel, timing, shift points) for more power and a different feel - no tools or mechanical work needed, unlike most other mods on this list.
why this one — Comes with pre-loaded 50-state-legal tunes (so it will not fail an emissions check the way an off-road-only tune can), plus it doubles as a gauge display and can read/clear check-engine codes.
Retailer description says it "improves performance" but states no specific hp/tq number, checked 2026-07-11.
