Increase your Vehicle Horsepower, Torque, & Fuel Mileage by Enhancing Factory ECU (Electronic Control Unit) Electrical Performance. 

Factory ECU controls your vehicle functions through electrical current such as: air conditioning, navigation, audio, lighting, engine alternator, valve, and throttle switch, transmission, spark plugs, fuel pressure, and all engine combustion processes. 

Changing in engine rpm and alternator can't switch from charge to discharge rapidly enough to quell small-scale voltage fluctuations or electrical "noise" in your car. This can adversely affect your car's electrical components & performance. For example, when you turn on your vehicle's AC (air conditioner), you'll notice car engines lose power and acceleration. This problem is happening in today's modern vehicle as well.

By Eliminating any electrical noise fluctuations' supply to factory ECU, your vehicle will definitely get Increased Power and Torque throughout the rev-range. Very nice.
