The stalling issue sounds like the bypass valve has failed- if you don't
know, it's the plastic valve that
sits to the passenger side of the engine near the very front, behind the
intercooler and near the turbo.

The overboost issue could be several things, you need to do some checks-
pull codes, see what the
computer thinks; pressurize your intake tract and check for leaks; replace
any hoses that are leaking;
do checks on your sensors. www.sjmautotechnik.com is a great resource for
diagnostic info as well as

Also, if your car is chipped, you really should find out what you're
running- whose software?
