I see a T on the line going to the boost solenoid. Any Ts should be on hoses from the manifold nipples since I expect them to go to boost gauges etc. If the third hose is leaking, you will get overboost issues.

That's your problem there.

Your boost control hoses should be like in the linked page:

well i just checkd the bottom pipe of the solenoid goes to the inlet turbo pipe. n top one goes to the manifold left nipple :P n the other one goes to the dump valve. then the boost gauge pipe comes from something else that looks like a tap n with a T connector another pipe goes to the right nipple on the manifold.
will i need another t connector to connect a pipe from the top pipe of the solenoid to the actuator turbo pipe?
