Lack of power and turbo boost

[Saffe]

Saffe just thought wastegate creep could cause your problems though it would have to be quite severe , have a look here about fitting a boost controller which would cure it if that were the case .

Hello Shayne (and the rest of you)

To close this thread I eventually (a half year ago) found the problem... It was the valve of the waste gate that didn’t closed completely. When I dismounted the bracket that holds the valve rod (and by this action it closed the waste gate valve) I heard the turbo spinning up when engine runned at
idle.

Thanks again for all the help
