i had a service kit today as my forge dv was not making a sound? took it apart and fitted the new seals spring and greased. Still nothing?? what else could it be?? all im getting when i come off boost is chatter which im guessing is air being forced back at the turbo which is not good

 

heres some photos, the dump valve didnt work when i bought the car does this all look right?

 

them, when i started the car the it wasnt idleing right, eventually settle but when reved idled up and down then settled so ive put the forge back on. i reckon theres a boost leak?? please can you post photos of your dump valves so i can check the fittings again
thanks
