Aug 22, 2010 update on ditchdigger's 1971 Fiat 850 Berlina

One TDO3 Turbo from a Volvo S80 Bi-turbo, one 1G DSM intercooler and BOV. For some reason it takes doesn’t start making boost until 4000RPM and only makes 4.5psi at 7000RPM. I need to double check the wastegate and make sure it is not part open.
