So we are in the process of purchasing a new toy hauler. I have been talking to a friend that has a 16 Silverado he pulls a toy hauler with and he purchased a edge programmer. He says it improved the overall drive ability of his truck. Says he gets better fuel mileage while towing his camper and he suggests that I buy one for our 2012 Silverado. I have been doing some research and don’t find many negative reviews on them. I also like that I can turn off the active fuel management, I have read that it can lead to problems with valves and possible engine failure. Now our truck is not high mileage, only 62,000 miles. We don’t drive it in the winter, only really used for pulling our current trailer and home improvement runs, and taken to work some times over summer just cause. With the prices of new trucks a new one wont happen for a few years. Does anyone have any experience with the edge programmers? Would you guess consider putting one in your trucks?
