1986 944 Turbo Boost Problem

Engine

Vehicle Information: Model(924/944): 944T; Year: 1986; Engine (type, size, modifications): Standard Porsche 994 Turbo for 1986, with no modifications I know of.; Total Mileage: 65000;

I have a problem with turbo boost. It goes as high as 1.3 to 1.4. The turbo is new, and I personally just replaced all the vacuum lines, and the cycling valve. I also checked the KLR light codes per the Porsche manual, and there are no lights to signify a problem. I then blocked off the tube from the cycling valve to the wastegate, and the turbo spun up very rapidly, so I assume there is no mechanical problem with the turbo. Any thoughts would be appreciated.
