i get out of my car today and my turbo timer was on so the engine was running . i herd a strange hissing sound coming from the engine bay. i poped the hood and noticed that it was coming from the vac line on my internal wastegate. i dont know why this started today...are boost controller solenoids supposed to be open all the time under vacuum? this was at idle of course. thanks.

bump for this , i fixed it , now it goes to my target boost then immediatly goes to stock 5.5 lbs of boost , what the hell!!!!!!!!!!!! could it be the vacuum line from my internal wastegate to my boost solenoid ???? could it be collapsing?
