i have a 2006 silverado and am trying to go 3 bar. HPtuners told me that the 06 pcm is not capable of handling the space that 3 bar would require. Is it possible to download a 05 OS, license and install it? Is the 2005 able to support 3 bar or 2.5? anyone else had to work around this issue? 2 bar will not be enough for what I need unless I want to make educated guesses, which I dont.

ended up figuring this out on our own. Basically if your truck is not 3 bar compatible, then what needs to happen is you need to search the repository for a same year truck and see if theirs is compatible. Basically we found a 2006 Silverado ss that was 3 bar compatible and just did a write entire. The computer accepted it and we are tuning into boost now.
