Review on 🚗 Advanced Fuel-Saving Performance Chip/Power Programmer for Subaru WRX & WRX STI 2.0L and 2.5L - Maximize MPG, Save Gas & Boost Efficiency, Amplify Horsepower & Torque! by Keith Samuel

While researching this chip I was skeptical and then found this article which breaks it apart and shows it's just a resistor, connected to 2 wires. It's not a microprocessor (which can actually do anything), it's not a soldered-on, glued-on resistor package that costs 75 cents. Kudos to the inventors as I'm sure they have made thousands of body resistors and sold them to people who can't afford a $500+ dyno to prove 35 horsepower. - complete nonsense.
