If you have the reflash done does it still show up on the GM cali site? Do these updates actually update your VIN on that site?

I had some stuff done (parking lot surge, fuel filter DIC) but I dont know if they did anything else. Everyone keeps talking about how quiet there LLy sounds now I really didnt notice anything quieter, just smoother.
thanks for all the help,

Jas

Entering your VIN only shows what updates are available for your vehicle and not what you actually have. Computer must be read to see what you actually have. ;)

how do i know if any updates are available, i havent had anything done to the computer since i got my truck in september of 04

This is the link to find out what updates are available for your VIN (you must have the computer read to find out what's in it):
http://calid.gm.com

Which leads to this updated link:
