Review on Innovative Performance Chip/Power Programmer for Chevrolet Aveo 1.6L - Enhance Fuel Mileage, Save Gas & Boost MPG, Increase Horsepower & Torque! by Pop Henneghan

Complete Scam! Do not buy! It's just a resistor packed in a fancy box. This will make your car think it's colder outside, giving it more fuel. Now as the car warms up the O2 sensor will detect that it is too rich and bring the fuel back to normal. The fact is that it acts on the car only when it is cold (about 2-3 minutes). Complete scam! It only has two wires connected to the ambient air temperature sensor. This means it doesn't get any power to run the computer or processor, it only affects the resistance of the wires. Another scam DO NOT BUY!
