Not sure if it will help or not, but you can give it a shot. I know there was a member that moved here from out of state and had to adjust his. Might want to check your vacuum lines also. I know some cars had signifiantly low boost from the dealership and it turned out to be a vaccum line that had gotten disconnected.
Hope that resolves your issues. No Cobalt should go without 12 psi.
