Can you hear the compressor? I've got an aluminum CAI and it amplifies it a LOT. That lets me hear if it's actually compressing or if the belt is slipping. I've had mine up to 7 or 8 psi with the belt tight (I've got a boost gauge) but 6 psi is pretty standard. The only way to get more is to do more rpms on the pulley (need to get a smaller one or raise your rev limit) or get a bigger crank pulley (no room, doesn't exist).

You may also have a leak somewhere that gives out at 5.8 psi. Did you have fresh gaskets when you installed it?
