As anyone heard or used the chip from usdiesel? It uses shims in the fuel valve and then a plug in controller. It is adjustable o-100 hp I have not heard anyone say anything about it. With the cost of it and a Edge Insight it comes out to be about the same price. Also you that have put chips and programers in your vehicles, now that you have had them awhile do you still think it has improved your fuel mileage?
Thanks for your input
