tempramental turbo

Right guys more problems lol It seems the turbo on my car seems to be quite tempramental. One day i have boost the next day i don't. I thought it might be a boost leak so i started replacing and securing the joints so i'm sure they are ok. Also replaced the dump valve as it wasn't holding as much boost. Is it more likely to be the hks actuator, wastegate, boost solenoid (apexi controller) or worse the turbo? A mechanic friend said he's not sure but as it works then doesn't then works again it might be the solenoid.

Any ideas? Hope it's not the turbo, theres no play in the shaft but there is a little oil in the pipes. The lad i bought it from said it has a hybrid ct9 turbo but i got nothing to prove this.

probably the solenoid alright jus disconnect the solenoid and put back to factory set up and set the boost using the actuator and if that solves it you need a new solenoid
