High Altitude help

Some of us unfortunately do not live at or even close to sea level. I personally have air here at about 5000ft. We generally lose about 2 pounds of boost. My guestion is would a pulley change to get some or all of that lost 2 pounds back set off codes or put into limp mode? Thank you in advance. And if not which pulley and maybe who could make them. One last thing is the belt a dodge specific or can you get something aftermarket in different sizes?
