HELP - boost issues on GT4 - solved!

The GT4 is all of a sudden running like a dog...
The car:
Stock engine/turbo. No boost controller. Aussie DP. Boost gauge.
Background:
Car has been running great, other than a bad O2 sensor causing a rich mixture (new sensor on order), and an error code 13 (RPM signal) which I think is cos of the dodgy O2.
I did some work on the car yesterday - added an extra bolt to the DP/turbo to close up an exhaust leak. Also tightened the throttle cable nuts cos I discovered it was loose. Nothing too major, but...
Symptoms:
Now, as soon as it gets any kind of boost (like anything above 1psi), the car jerkily hesitates like nothing else, & only reaches about 3psi/4psi/6psi in 1st/2nd/3rd gears (should be getting about 5psi/7psi/11psi). Car pouring out black smoke at max boost.
The symptoms sound like it's gone into limp mode, but not sure that explains the jerky way it's running.
I thought I may have knocked a vacuum hose or something loose, but have checked everything. Engine runs fine off boost. Reset ECU to no avail.
Any ideas?
