My truck gets pretty crappy gas mileage so I purchased a ScanGauge to optimize my driving habits and save some gas mileage in the process. Instantly just by seeing realtime how the vehicle responds to different conditions, I was able to boost my gas mileage by 2MPG. Add in all the other gauges and code reader and I can say I am very pleased with this purchase. I would recommend this product to anyone who does not have a vehicle that tracks fuel economy and may need a code reader at any point.
