I've just remove the Turbosmart manual boost controller from my 93 wrx import. I plumbed the old solenoid back in after cleaning it out with carb cleaner along with the pipes. I have a Z4 ecu. I only seem to be reaching just under 0.7 bar max whereas before I was getting 0.9-1.0.
Is there anything imparticular I should be looking at, I've checked all the pipes, think I have them the right way round:

3 port solenoid

-top hose going to turbo outlet (back of the inlet just after the intercooler)
-middle/side hose going to turbo actuator
-bottom hose going the air resonator box, with brass insert in

Anywhere else I should be looking??

Cheers
