Default focus rs mk1 help

hi i have a frs mk1 with cat back exhaust, pannel filtter and bluefin.
the actuator was knackered so was replaced with a forge 1, the pproblem is the boost still drops down and then back up and stays there. any ideas why it would do that, also with blufin what psi/ bar should it be running.
thanks kieran
