hmmm... vaccum leak would have other problems besides just low boost psi.. vaccum leaks also cause odd idles..

what are u idling at??

 

So your intercooler was cracked?

 

??

i had to much trouble reading that one lol

 

thank you very much for everyone trying to help me here. my boost level back to normal since i replaced the ecu, intercooler, and the Y pipe, and boost solenoid, i know too late to reply thank you for everyone was trying to help me, but still, THANK YOU VERY MUCH, I LOVE THAT CAR.

 

glad to hear the car is doing great

 

I had a similar problem with having to much engine oil, my dipstick said a quarter over low so added about 2 litre's which over filled it according to a subaru dealer, it just didn't doesn't want to spool up at all, removed some oil, work's fine I don't think they like having a full oil reading, yet too little scooby go bang

 

I know what it is go to Subaru dealership at the parts desk and ask for a restrictor pill or I think they call it a orphus pill but anyways you put it in the little vacuum line that come out and bends in front of the turbo and it will boost all the way I had that same problem
