Rubber hose to the turbo? No, it's probably to the _wastegate_. There's a
thick rubber hose of about that size running from the lower section  of the
wastegate to the wastegate frequency valve. Connecting it should make a
difference, unless the frequency valve itself is kaput (technical German
term), which is common in 100 kmile cars. In that case the boost is limited
to only about 1.4 bar.

Drop me a note if you're in need of a wastegate frequency valve--I have a
brand new one available for a very good price.
