question about hpp3 and tune i am trying to sell a hypertech and have it loaded in my car, however i also just got a dyno tune. i want to unlock the hpp3 so i can sell it and it have some use. will this mess up the tune, and if it doesn't, how do you go about unlocking it?

you should have had the dyno tune after unlocking the hpp3 I'm afraid 
the HPP3 rewrites the stock calibration back to the PCM in order to be unlocked...
There is a post in here though on how to unlock the PCM w/a Tech 2 ... I will try to dig it up
