When King was doing my tune he kept thinking my belt was slipping but maybe I was bleeding some boost out of the catch can. I think I might need a check valve on this line that will allow it to pull vacuum but stop it from bleeding boost.

I checked my own routing and yours seems correct. There should be a check valve already on the line that goes to the intake. In my mind it should allow air to pass from the catch can to the intake, but close under boost and not allow air to pass from intake to catch can.
It should only vent the crank case, not boost from the intake. It should still "suck" air from the crankcase through the catch can under vacuum, but vent the crankcase to atmosphere under boost while closing off the line to the intake.
Hope that makes sense. Again, routing seems fine. Id check the check valve on the small line on the can. Should be in the small AN fitting on the can.
Also maybe check that the valley port, where PCV is (or was) is closed off.
