I have HPT and there was no special unlock other than the credits you purchase to gain access to your PCM via the HPT software. Now the TCM is locked and must be shipped or exchanged with HPT to gain access to it. (along with credits.)
The cost of the the tune is dependent on the tuner. This of coarse can vary depending on how you to choose to tune also. And of coarse you need your flex sensor kit.

Thanks for the info! And yeah i'm probably going to order the kit once I find someone who can tune it
