I had my 98 corvette tuned by thunder racing, well, they went out of business and I have this hptuners ready to roll. So now that they cannot flash it back to stock and I do not want to pay the vampires at the dealership to do it I am lost. There are several stock tunes in the repository but can I trust them. I am new and I don't want to start off with a fried computer. I don't know what is the best way to handle this. Do I just completely write over the tune?
