i was just driving my car, everything was good. i just shifted into 3rd, and i heard the blow off valve. right before i was about to shift again, and it sounded like the blow off valve again and there was no boost !!! i can't even hear the turbo boost anything . i checked all of the vacuum lines, and there are no signs of anything odd in the engine bay. no vacuum leaks. any help would greatly be appreciated! thanks

 

I bet one of your intercooler hoses popped off. Check all of them..
