Exclamation Unknown problem??Help

My wife was coming home from work this afternoon, and said the car would not go over 20mph. Oil was just changed a couple weeks ago. Oil level is fine, tranny fluid is at proper level. I can't seem to find anything. It is also raining here.
Anyone have any ideas or same issue?
Thanks

Turbo?
If so did an intercooler hose blow off?

At the top of the turbo,top of the intercooler and bottom of the intercooler. Also make sure the one going into the throttle body didn't blow out.

I had mine blow out at the wrong time once.

I've blown one at the throttle body also. Think that may be the weakest spot in the system. You should be able to hear air leaking while under boost if you have a leak after the turbo.
If there's a leak before the turbo (between turbo and air meter) it could also be your problem.

well, turns out it was the large 90degree hose at the top of the radiator that connects to the air pipe that runs to the throttle body. Blew a hole right in it! Of course, need to get from dealer, but easy fix. Thanks all.
