Is there a way to unlock a vin locked computer and reset it to factory settings?

If the pcm is tunerlocked you could lift the chip from the board & flash it on a chip burner. There are a few vendors that do this service ie frost, pcmforless I belive, not sure if any of the sponsorts on PT.net do it though.

A tunerlocked pcm changes the seed/key in the chip, meaning no dealer and no tunershop can flash it using the stock seed/key. Tech 2(dealer tool of choice) only knows the stock seed/key so it will not be able to flash it.

Well it's a Nelson tune and I emailed Allen to see if he would turn it back to stock for me and I ain't got a reply yet so I was wondering if there was a alternate route I could go
