Ok. Which part of "locked" eludes you? I'm not trying to be an ass, (for once), but it's locked. Encrypted. The didn't want people messing with the tune... take your pick. Most of the other stuff out there is not "locked" or password protected.
Chances are that engine application just isnt sought after for performance upgrades. I mean, look at the poor LS guys. Short of an intake and some other bolt ons, there really isn't an aftermarket for them. I'm talking performance aftermarket, not bling bling aftermarket.
Your best bet is to call the ponticrap division of GM, and ask them why they locked the tune/computer. Chances are you wont get an answer, but you never know.
Now, I am a firm believer that once a car is out of manufacturer's warranty, the owner shoud be allowed to make whatever changes they want to the tune... even if it's a change that will blow up the motor. But while the car is under the factory warranty, you really don't have much of a leg to stand on questioning them why they locked the computer. After all, would you like to be a car manufacturer, then having the customer expect you to fix it after they effed it up by changing the tune?
I don't know much about those pontiacs. maybe the tranny won't take the full potential of the motor. Maybe the... maybe... oh hell, you get what I mean. I'm going to bed. I had way too much fun today in Denver.
