How To Tell If Turbocharger Is Working OK? S70

I recently broke a vacuum hose on my '98 S70 GLT (84k miles). I was told that the hose regulates the turbo wastegate and that if it was broken then I would get no turbo boost. Seeing as how the turbo on my car only adds about 10% to performance (168 HP - 190 HP) and since I really couldn't tell a difference from when the hose was on and when it was broken I was thinking that it might have been out of commission all the time (I've only had the car about a month). Does anyone know an easy way to tell whether or not I'm getting turbo boost?

Do you hear a hissing noise or a noticeable change in performance?

If not i would suggest taking it to a shop that works on Volvos or to a dealer to be sure.
