A device called Fuel-Pro and produced by a company off-shoot with Elon Musk, is promoted as almost doubling gas mileage for vehicles made since 1995. It plugs into an access port that allows fine-tuning of the engine performance, and the device loads proprietary software that is claimed to greatly increase efficiency of fuel consumption. Is it effective as advertised?
