How to get PCM unlocked?

[GasGuzzler]

Try it and see , that would dispel any myth about locking PCMs , and if you want I will lock one with EFILive and you can try it as well (I can reflash mine for free) !

When do you wanna come back up and try it? We can do the Blazer or the Denali.

Any time after Tuesday of next week .
I am pretty confident that you can not flash it seeing the boot loader is shut out and any attempt will be rejected .
