May 20, 2010I have a 2007 LBZ Duramax and was wandering what the best programmer or tuner would be. I am mainly looking for better mileage then more power. I have been looking towards either Banks or Edge, but i did see this site www.powerupdiesel.biz that sounded interesting just not sure if its legit or not. Any help would greatly be appreciated.
