We have a 90 200QA with 213,00 miles. It's a very robust engine, but as
you may know, does suffer from a need to maintain certain aspects. In
any case, if your boost is limited by the fuel cut-off, it is almost
certain that the waste-gate diaphragm is torn. It's a  pain to replace,
since you have to remove the wastegate. You can test it with a vacuum
pump. If you are lucky, then the problem is just a wastegate hose that
has a hole in it.

Not sure if you have seen Scott <ockrey's site on type44 turbos, but if
not, you should read it. Many times.

Good Luck
