My auto shop told me initially I'd have to buy a new computer ECM for my truck and afterwards take it to the dealership to be programmed. That all would have cost me around $1,000 to do total. After finding Flashmasters I paid under $200 and they did all the programming for me and I was able to skip the dealership altogether!!! Thank you for cutting my cost dramatically and sending me a fully functioning plug in, ready to go module!
