So my friend knew this guy with a bullydog gt programmer and said he was willing to sell it, so I of course jumped at the offer for a cheap programmer and he said it works and everything he had it on his cummings and it ran perfect, well i get it home and the mother *(&^) is still tuned to his truck, does anyone know if i just got screwed or can i get bullydog to reset it for a fee? or can i rig it to work some how?!?!
