Just put turbo back on car went for spin up road and its not running any boost at all turbo not even spinning

and exhaust is louder than normal...It sounded and done the same thing on me old mans turbo when actuator bar fell off ive checked mine and bar is all connected.im running a bleed valve not amal valve.the car ran fine before i took it turbo off i only had a stud drilled out which had snapped in housing so dont no why its done this???? would it do it if there is not enough load on the actuator even though im running a bleed valve?????
cheers
