SuperChips re-use

Hi all.
A friend of mine has a SuperChips device that plugs in to the Tahoe interface (seams to be a rs232-serial port) which upgrades or modify performances and so on (well, you must know better than me what it does... :)
However, once he has upgraded his own Tahoe, he would like to upgrade another one with the same device. The manual says it is impossible but I am sure that a workaround exists. Does someone knows how to do that ?
Thanks a lot.

the device records the vin of the truck when programming.

And no way to reset it ? I'm sure that's possible... :shakehead

not that i know or heard of, most replace stock with performance program, and then hold stock program in programmer so even if you could trick it you would be replacing your stock program with his stock program.

Bad luck. There should be a way but that will be tricky.
Thanks anyway for the reply.
