Here is the updates for my 2005 LLY. It is still sitting at the Pontiac Assembly lot. Here is the calibration link http://calid.gm.com/vci/SuppCont.do?BTNSUBMIT=back

I went to the link and looked up my vin# but i did not know where to go in order to find out if there was anything i needed. I had a list with a box that have normal on it what will this information do for me?

click on PCM/VCM in the upper box "SELECT A CONTROLLER"
then click on normal in the "SELECT A PROGRAMMING TYPE" box below that, then click next. You will likely get a list....click on the ENGINE box and it should give you what you need in the HISTORY box.

Hope this helps:ro)

In the history box, does it show you what was done, or what is needed? Mine looks like yours and it was built on 10/20/04.

Buck,

I think you will find that this calibration is already loaded. Mine is current. I believe that this ID site only shows what is available, and you need to verify what is loaded. The Predator can actually show you this stuff as well.
