Ok looking at all the power modules out there I am getting dizzy trying to keep track of which modules do and which models do not store codes to the computer so when I go to the dealer for any reason they don't figure it out and tear my waranty up. I have looked at the banks six pack, Van Aaken, Bully dog, and a few others. Have hear more than a few reports on the B Dog and they were bad so I think I am going to stay away from them unless they have recently fixed old problems. Heck I found their boxes for as low as 440 bux plus 15 shipping, cheap but I know you get what you pay for.any help thanks
