Doesn't sound like anything major. I would check all of the pipework from your turbo and actuator to your boost solenoid and make sure all of the pipes are on correctly and they don't have any splits in them.

It sounds to me like it is overboosting and hitting fuel cut.

Did you find the cause of the engine failure ? Whatever it was needs rectifying or the new engine may go the same way.

Also, it is worth spending £70 or so on a new air flow meter on that model year as they can fail causing lean running resulting in detonation and engine failure.
