A few months ago I corrected one of my Kodiaks that had a slight lower limb twist. Instead of holding the bow under hot running water, I filled one bucket with really hot water and another bucket with cold water. The hot water was so hot that I cold just barely keep my hand in it. While the bow was strung up, I put it in the hot water bucket for about 4 or 5 minutes, pulled it out and twisted the limb until straight, then submersed it in the cold water bucket for a couple of minutes. I had to do this three times before it finally stayed, but is is on good shape now! I think one of the key things is to leave the bow strung up for a few days afterward.
