This is my first post so bare with me. I have a 2006 GMC Sierra with the LLY. I am wondering what is the cheapest way to get a stock Lbz Tune loaded. I don't have any tuners on the truck. I just want the stock LBZ Tune for now. I am driving to California next week and would love to try it out on the drive. Again I am cheap and have been quoted $350 for a single tune?. I hope that's not the going rate. I tried the dealer as well. They claim Vin issues blah blah blah. Thanks guys.
