Hi Any one tried the tuner module from this company? http://www.powerupdiesel.biz/category-s/119.htm Thanks, Dave

I would steer you towards a reputable EFI Live tuner for the Duramax. Check out some of the Duramax forums to get the specifics but I doubt you will find anything better to use than EFI Live.
