Tried to scan/tune a 2003 Cadillac CTS with a 3.2 v6. Would not let me read the ecm or use scanner. It said there could be a possible issue with the VCM or the vehicle was not supported. Was curious if it could be tuned or if the customer is out of luck with your software. Thanks!

Not a supported application, you will not be able to tune this application. You can find a full list of our supported vehicles here https://www.hptuners.com/vehicles/
It doesn't have to be perfect, it just needs to be done in two weeks...
