Great Price, Great Company, could be better
This is a good product when it comes to the calibration of your vehicle if you have upgrades such as wheels and gear swaps. This is also a great product for the use of the driving coach. Although, The one downside to this product is the installation time of taking approx. 35-40 minutes and it didn't improve my fuel mileage as much as I thought I would. Maybe 1-2 more mpg. The product also requires update through a computer which is kinda a pain especially for those Mac users. Also, For my 14 Silverado 1500, I cannot find a tune in the device to use for economy. This product does not give me tunes, instead I have to choose features such as performance or tow for each individual aspect, Engine and Transmission.
