Review on 🚀 Innovative Performance Chip/Power Programmer for Hyundai Genesis 2.0L, 3.8L, 4.6L and 5.0L – Boost Fuel Mileage, Save Gas & Gain MPG, Enhance Horsepower & Torque! by Reginald Holman

STAY AWAY, STAY AWAY, AVOID. This is nothing new, maybe the best scam in the automotive industry! It's a useless item that tricks your engine into thinking it's cold outside (and it is all the time). It's pointlessly increasing fuel delivery at idle. In many cases, performance has been lost, doing more real harm than good. Others report it and engine/service engine warning lights on the instrument panel come on shortly after installation. It's a very small plastic box, about the size of a TicTac box, with a .39 cent resistor that you can buy at Radioshack, with two output wires that you need to connect to a sensor in your car's intake system. However, there is a guarantee that comes with this product: you will definitely regret your purchase!
