Review on 🚀 Enhance Fuel Mileage, Save Gas & Boost Performance of Infiniti G25, G35, G37, Q40, Q50 & Q60 with our Innovative Performance Chip/Power Programmer - Upgraded MPG, HP & TQ! by William Byrd

I returned mine because customer service did not provide the color code required for installation. I was researching these so-called programmers and found this. They connect to the IAT sensor (Intake Air Sensor) and fool the computer into thinking the air is cold. In response, the computer sends more gas to the engine. This effect is not permanent, and over time the computer will adjust to compensate. In fact, your car will use more gas and only get a minimal increase in horsepower, somewhere around 2-3 horsepower. This is a waste of time and money and can permanently damage your engine. Check them out on YouTube and you'll see what I'm talking about.
