Back once again like a renegade master

i hve found this do you think it looks right a pipe from the turbo to the pipe at 12 oclock in the top pic and the normal vac pipe on the pipe at 9 oclock

no longer a series, but still 1.3 turbo.

look to me like it is a bypass valve like what is fitted to superchargers to stop them developing losts of boost at low revs/idle? (or atleast i think that what they do)

that would explain why you are losing pressure. maybe?

EDIT: what happens if you block of the pipe at 12 o,clock but keep the normal one that see vacuum?

from what i can make out the boost sensing pipe will just raise the piston/diapram up as you make boost so venting to atmosphere. like a sort of wategate?
