It did pull 28-30psi before. I'm going to have the turbo retested and see if the turbo or actuator is failing.

A CM2350 should be about 36~ish or so psi if not de-mandated.. and de-0mandated, no more than 33 psi max on the boost. The numbers you are quoting are far too low.. even when you did think it was running ok.
