What Does This Do?
A tuner is a handheld device that plugs into your car's diagnostic port (OBD-II, under the dashboard) and can change how your engine computer operates. The inTune i3 comes with pre-loaded performance tunes that adjust fuel maps, spark timing, and transmission shift points for more power. Benefits: noticeable improvement in throttle response and mid-range power, easy to install/uninstall, supports data logging so a professional tuner can write a custom tune. Trade-offs: loading ANY tune will flag your PCM as 'modified,' which may affect your factory warranty. The pre-loaded tunes are good but not as powerful as a custom tune from a professional. If you plan to add bolt-ons (intake, exhaust, headers), a custom tune that accounts for all your mods will make significantly more power than canned tunes. Think of this device as the delivery mechanism — the real magic is in the tune file.
