I was at the truck show today at the San Mateo fair grounds that was sponsered by four wheel parts. While browsing through the vendor booths I stopped to talk with a BullyDog rep. He told me that BullyDog has come up with a way to tap into the OEM computer and download new programing. He states the stock computer has the ability to put out some serious HP and TQ numbers with new programing. He showed me a brochure of the one they use for the Duramax, and stated to look for more information on there web site by summer. The bombing wars are making it difficult for me to decide on which product to use. Every time I think I have the box I want, someone changes the rules.
