I have a flashpaq i plan on running til i get efi live, and had a question. I was told it's possible my truck had a different programmer on it when i first bought it, and read that the flashpaq will save the factory tune will replace it in order to lock it. Does the superchip load a totally fresh tune onto the truck or does it build off the currently flashed file? Thanks
