You will need a gun that can generate enough torque to do it. I had to go buy a new gun the last time I took mine off because the one that came with the compressor couldnt cut it.

Mine say 90psi, but I run them at about 150psi. If you're having trouble, you could put the wrench/socket on the bolt and whack it with a hammer. One good bump will usually loosen anything. 
I used an Ingersoll Rand impact at a guys shop that was so powerfull, that it actually rotated the world instead of the bolt. I swear it had to have been running on 4000psi nitrogen or something......
