Could have got some crap in the boost solenoid when the pipe burst. You can clean them with brake cleaner or petrol as far as I know. Don't use either till you check with someone more knowledgeable.
 
Double check your turbo intake pipe has not spilt/ripped.. This would give erratic behavior you were experiencing..

But without seeing very hard to say..........
