hi to you all first thing is i can not get my car 99 turbo 2000 over 9psi boost i have cleaned the boost solenoid and the checked all the pipes had new maf and knock sensor . the cel shows no fault. so im stumped any help please

 

Are you SURE you have got all the pipes exactly right? In my experience get even one pipe wrong and you get stuck at 8 or 9 psi, in other words the actuator's spring pressure.

The small brass restrictor should be in the line from compressor outlet to the T. The line from the T to the actuator input should be empty, just a plain pipe.
