wont hold boost

my other pulsar wont hold boost, its set up for 1 bar and when it comes on boost it boosts to 1 bar then drops off in the midrange then picks up again higher in the revs :? ive tried using a bleed vlave and it does the same thing so that rules out the boost controller being the problem. Any ideas?

im thinking it could be fooked actuator?
or cracked turbo exhaust housing (around the wastgate housing)?
