Do predator tunes "lock" the pcm?

[triggerjerk]

Hi all,
I may be getting a predator (revolutions) tune from a local tuner. I was wondering if after it was tuned if the pcm became locked. I'd like to be able to tweak it in the future with ls1 edit instead of going back to the tuner. Will I be able to do so?
Ideas?

I imagine you will have to go back to stock before using ATAP

Predator doesn't not lock the PCM ... but I would not want to start using EDIT from an already altered PCM file (that was altered with something other then EDIT) . If you start running into problems you have no STOCK program to reference to try and diagnose where the problem lies, you could potentially go around in circles for hours without happy results :)

Ok.
Here's my problem. I have already tinkered with the pcm via edit after my cam was installed. I am thinking about getting headers and gears soon. I no longer have access to edit though. There is a diablo tuner about 45 mins from me or raging motorsports (uses ls1 edit) which is about 3 hrs away. So basically I want to be able to find a good tune for the headers/gears that will also allow me to make changes in the future if I decide to go for more mods...
thx

predator will only allow you to edit one car. It will lock onto one vehicle if you do any edits

If you have an EDIT adjustment/tune already I would stay with it .... or get your stock tune back in (you do have a copy of it, right?) and start with something else but I would not mix tunes :(

Yeah, i'm not sure how the tuner is doing more than one vehicle with the diablo software....
I'm just worried about the actual pcm being locked out like some others have done...
