redz, the theory behind these "chips" works. leaner conditions will give you more power, rich conditions will actually give you less power. these chips make the ecu think LESS air or WARMER air is going to the engine, which makes the ecu think less fuel is needed. less fuel will give you lean conditions, which will give you a higher EGT(exhaust gas temp.). a higher EGT will give you higher exhaust gas velocity, which will give you more power. the problem with a higher EGT is that the extra heat can cause holes in your pistons, which lead to hot spots that can eventually kill your engine. to much fuel will do nothing more than keep your engine a little cooler, decrease your gas mileage, and crap out your emissions.

The HorsePower Performance Booster replaces the sensor that tells your vehicles computer how much cold air it is taking in, this in turn will alter your fuel and timing curves, The HorsePower Performance Booster adjusts your fuel and air ratio to run more efficient , Your Computer will respond to the Performance Booster's reading with increased horse power (With a Full Potential of 20hp) This Performance Mod will allow you to boost the power output of your vehicles engine, without sacrificing reliability or comfort. This is the same technique that expensive performance chips accomplish but the HorsePower Performance Booster will allow you to replace the sensor instead of having to remove your vehicles computer, the cost is substantially lower but the end results are the same. By Tricking your vehicles computer it will make it think it is under heavier load and increase your horsepower

By fooling your computer and letting it think that you are sucking air at a different temperature. Your computer will respond with increased power!

What is this Device?
IT is a resistor chip that gives out a constant reading of air temperature to your ECU.

This mod will modify your stock ECU with a Timing Advance resistor. This resistor connects to the car's ECU by replacing the Intake Airflow Temperature (IAT) Sensor. Once the resistor is installed, the ECU will read that the air coming in through the intake is cold air; think of it as a "default" setting on the ECU. When the ECU reads this, it lean out the air/fuel mixture-in other words, it will take in more air, and then add more fuel to compensate for the extra air coming in, thus, producing more power and advancing timing 1 to 2 degrees. Because the engine is creating more power, it will need more fuel; so the fuel economy on the car will decrease 1 to 2 miles per gallon (MPG), but definitely not more than 2 MPG.

Once this is installed the ECU will read the air coming through as colder than it really is. After reading this, it leans out the air/fuel ratio, meaning it will take in more air and then add more fuel to compensate for the extra air coming in, thus, creating more HP and advancing your timing 1 to 2 degrees
