I have got a 2000 Corvette with a OS 12593359 which only has 2 custom OS available whereas a friend has a 2000 with OS 9381344. It is my understanding that for P01 0411 PCM's that OS 9381344 is a much more desirable OS because it supports 4 custom OS like 3 bar map and RTT. I have licensed my car already. Whats the process for getting the 9381344 OS on my car? If more information is needed please just ask
