i got a superchip flashpaq today from a friend, he used it a couple times. but it has his vin or whatever locked into it. how do i use it?

you cant until its unlocked

well yea.. but how does that happen? anybody do this before and can tell me what i gotta do?

either you have to find the original truck and take the tune out or you have to call superchips and see what they can do to help you... and that route is gonna cost ya $$

put his truck back to stock tuning. that should unlock it. (basically what rdeterman said)
