GI.SS Posted April 23, 2015 Report Share Posted April 23, 2015 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.

chpspecial Posted June 2, 2015 Report Share Posted June 2, 2015 No, the 05 truck has a different TAC and pedal assembly. The 05 os will not work on your 06 truck unless you use the 05 TAC/peddal assembly. Quote Link to comment Share on other sites More sharing options...
GI.SS Posted July 22, 2015 Author Report Share Posted July 22, 2015 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.

Krambo Posted October 27, 2015 Report Share Posted October 27, 2015 ...interested to see the set-up that REQUIRES the 3 bar set-up. Must be a beast. Quote Link to comment Share on other sites More sharing options...
