I just bought my first duramax. It's a 2005 with 67000 miles. The truck came with an existing tune on it and I'm trying to find out the best way to go about getting the old tune off. I know I'm going to buy efi live soon but I had a friend tell me I have to the old tune removed first. Any help would be greatly appreciated, thanks in advance.

Do you know the cost associated with having this done?
