Ive searched and searched. I have a 2006 Silverado and want to run a 3 bar OS. The box is grey and I can't choose 3 bar. Support told me that the 2006 computer doesn't have enough room to support 3 bar. So what are my options?

The pcms are the same from 2003 to early 2007, 2003-05 have 3 bar, so pcm is capable. You MAY be able to switch to a 2005 o/s but you will have to research to see what the differences are BEFORE you license and flash any other file in.
has anyone tried to license and install a 05 OS into a 2006 pcm and it actually worked?
The only 2006 P59 OS that supports 3bar is the 12587811 OS that I know of...

It's not the PCM it's the OS which can't support the 3 BAR. I have converted several PCMs to 3 BAR but I had to flash a different year OS. If the VIN mismatch is not a concern you can flash any 2003-07 OS with 3 Bar support and it will work fine.
All P59 PCMs and files are 100% interchangeable, I have tried many times and it always works. Unfortunately it's always a tradeoff

What type transmission do you need the OS for? I have some 2006 files that are capable of 3bar with the OS I mentioned above.

I actually am running into this as well. I have a 2006 Silverado to tune (4L60-E for now)...going to start with 2-bar, but it'd be nice to be able to go to 3-bar.
If I e-mail you the guys VIN number, can you send me a base file back?
No issues with the rest of the computers in the 2006 truck talking if I change the OS...or even if I change to a 2005 OS?
