| Not many people will suggest stacking anything on a duramax. I don't know if the hypertech adds timing or not, but i know that the edge does. If the hypertech adds timing too i would not stack the two together. Might want to call hypertech and ask if they add timing or just fuel. If you do stack them then start on the lower levels and work you way up.
