What is a Performance Chip?

Answer:
A performance chip is an after-market product

that you can place in your vehicle to maximize the horsepower and torque you get from the engine. Car manufacturers design fuel systems to be as fuel efficient and environmentally friendly as possible.

To accomplish this, vehicles are designed with engine control unit chips that hold lookup tables that the engines’ computers use to determine the rate of fuel to provide during certain driving conditions.

A performance chip replaces the engine control unit chip and raises engine power by imputing new lookup tables into the vehicle’s computer. This allows the engine to create as much power as possible because the fuel and ignition systems can consume as much fuel as is needed.
