Sending my pcm off to have it reflashed for a stall and cam, This will get me around till i get to the dyno. I have a diabo tune in it now. Do i need to return the pcm to the original tune before i send it off and reinstall my new tune when the pcm returns, and does this cost me ticks. The reason im asking is i pulled the pcm to ship it tomorrow then thought about this, Thanks.

 

return it to stock so you can sell the programmer... if you dont, it stays locked i believe.. like the HPPs do...
