GTO 1

Hello Guy & Gals....

I made use of this site to make sure i had the latest flash. If you want to know your calibrations see below:

FOR LOOKING AT YOUR OWN CALIBRATIONS:
here is the GM site:

http://tis2web.service.gm.com/tis2web

1. Enter your vin #, then click GET CAL ID.
2. SELECT "PCM/VCM Powertrain/Vehicle Control Module.
3. Click NEXT button.
4. Click Complete History Button.
5. New window appears with all the part #'s, double check them to check your reflash.
6. Print the new window page that appears and bring it to the dealership, explaining your flash is outdated and causing you drivability issues. Hopefully you are in the warranty time and miles to get this done free!!

I'm pretty sure that the CAL ID's that come up are the CAL's that you already have flashed to your various control modules. They aren't showing you updates but rather what you currently have, and what you had before .
