I read that too... But i'm not confinced about that idea...

I actually have a PE and i opened the valve with the golf tee mode already before i let the PPK installed. (European PE has a valve, American doesn't)

I think the best thing to test it, is to open the valve (you know now how) and open your window. Do some city streets. That should confince you... The burble should be there!!!
