I bought one for my 05 duramax about 6 months ago when I went to put it into my truck it needed an update so I plugged it into the computer and it froze. It took me 3 days to get it to update finally , truck has been shifting like a piece of junk running tranny codes and three injectors just went.I have just passed 70,000 km and parts like that shouldn't be going . I noticed more gain and better shifts with hypertech.
