More information please. Is everything stock or are there any modifications? Has this been a problem since you got the car or did it suddenly appear? Did you check for codes?

It's easy, so checking for codes is a good first step.

How old is your gasoline? How old are the spark plugs? Checking for intake leaks between the turbo and throttle body is in order. That's most likely to leak under maximum boost.

The TSRM troubleshooting chart can help with ideas of what to check.

When you say the car feels like it trips over itself, does the check engine light come on for 2 seconds, then turn off? If so, you're hitting boost cut.
