Just about every modern vehicle is equipped with an engine control unit, ECU. It's a little box that, in fact, controls and regulates operation of the engine, thus letting you experience the ironclad torque and fuel economy. The bad thing is that car manufacturers program ECU with an average driver in mind. No wonder why your vehicle doesn't operate at its peak, and why the high-performance junkies can't tap into the max output of the engine.
As you see, it is actually the on-board computer that limits your vehicle's potential. It's a strict censor that scissors all breath-taking scenes from a blockbuster. Performance chips are engineered to reconfigure your on-board computer, and thus, free your engine from the restrictive factory settings. You get optimum air-fuel mixture and ignition timing, change any settings you want and have fun behind the wheel and enjoy every second on the road.
