Answers :

I have a 2008 GMC Sierra 2500HD Duramax and use the HyperTech software also. I assume you are talking about the installation instructions for HyperTech where it tells you to remove the ONStar and Radio fuse. Look in the owners manual for the fuse box layout under the hood. On mine, it's in the Duramax book and the only fuse that applies is the one listed for the Audio System. You will need to reset your clock when finished.
