The turbo is fine if it's making 15-17 psi.
Tell us what vacuum hose came off? If that hose came off then youneed to know why it came off? Is it dry or rotten, loose? You may have to replace it, but tell us which one it is. You also need to check the big hoses on each side of the intercooler to make sure thay are not cracked, that the intercooler is seated in them properly and that the clamps are positioned properly and tightened.
