I am using a 2012 CTSV OS, so if there is another vehicle that I could segment swap from to make this possible I am all ears.

I am running a factory CTSV pedal and the throttle body from my LH9 5.3, which is the same part number as the CTSV TB.

Bill, does "write entire" on a T43 write the base OS? The local dealership wants $200 to flash my T43 so I would like to try it on my own beforehand if that is something HP Tuners can do.

I know...

As a continuation question: What is the process for changing the T43 OS? I think the correct order is:

Download a factory A6 tune from the repository
