Wastegate Hose Pressure Orifice

[josefigue]

Hi,Today I check my wastegate hose and note that the Y has no restriction orifice.They have the same hole in both sides without no metal restrictor.The Gm original have a restrictor.Which problems can cause this ?The pressure metal orifice goes to compressor or actuator?Do I need this pressure side?Please help with the answers.Thanks

Yes you need the orifice to be able to get much more than 14-15 psi boost. The orifice should be connected to the compressor outlet, not the solenoid or actuator. Also make sure that the second port on the solenoid valve is not plugged. It should be open or have a small foam rubber filter on it.
