Re: Found this GM site that displays all your ECM updates, etc. with your VIN!

Here may be a rather dumb question, BUT, assuming these are updates that should have been done:
1) How do you know for certain they were done?
2) How do you know if they need/should be done?? Really necessary?
3) Where do you get them done? I am assuming the Stealer? Cost???/Benefit??

THANKS
