I am working on tuning a 2009 CTS-V with a E67 and I am unable to find any other OS options under the OS selection. I wanted to do a 2 bar speed density, but there does not seem to be an answer. Does anyone know if this is normal or if I am doing something wrong? I have my personal 2011 CTS-V that has the option available. I planned to use my tune file and change the VIN to the 09, but that will not work either. Any suggestions would be appreciated.
The 2009 CTS-V doesn't have the 2 bar upgrade available. Not sure why though. Maybe one of the Pros on here can explain why.

The 2009 CTS-V service number is a one-year-only thing. 2010-up uses different hardware, can't put the calibration from one into the other.
