Is it underboosting or overboosting? I'm guessing under, right? In that case it will be stuff after the turbo to look at i.e. turbo, turbo-to-IC, IC, IC-to TB...

If it's overboosting, it will be a vac line of the boost control system - i.e. before the w/g act. - that has come adrift/split.

if it's struggling to boost and you can hear it you could have a leeak on the up pipe, I had a problem in getting boost, it would reach it but would be a a bit slower, and when i changed my turbo i discovered it was blowing

Yes, also as scoobyboothy said, it could also be a big exhaust leak pre-turbo i.e. uppipe or exhaust headers.
