It certainly is a problem in the boost control, but a lot of things can go wrong. Computer fault (driver transistors) is not the first on the list...
Sounds like a BPC valve problem. The (Trionic) ECU controls the valve, but....
Most of the times the valve has a "mechanical" problem and it needs to be replaced. You might also have a leak in the plumbing, check the pressure tubes carefully. Leaks and proper order. The valve is the black plastic thing that sits on the radiator. A three wire connector and tree rubber tubes attached. You can also have a sticking waste gate actuator, check for free operation. The valve has two coils, check for resistance between pins 1-2 and 2-3. Both should be around 3 ohms, I think.
A shorted coil might fry the said driver transistors, but this appears to be rare.
Search the BB for "base boost" and "fuel cut off". Most cases it's the BPC valve, it's expensive too, but not AS expensive as the ECU.
