To get u home can bypass manual boost control and connect vac (take off near alternator_side of eng block) direct to VNT vac actuator diaphragm.
Only do this if running boost gauge and drive to gauge _ Do not over boost"
Then if U still can not make boost, check hoses either side of intercooler but certainly does look like hose has dropped of controller. Have a look at boost take off (MAP sensor or somewhere on boost side of turbo.
