Vauxhall Combo 1.7D Y17DTL 2003 - No boost, no codes #

Year of Manufacture *: 2003 Engine Size and Code *: 1.7 Di Y17DTL ( Optional) Fault Codes: None
Good Afternoon Gents,
Complaint is Combo Van with no boost. No Fault Codes.
Actual & Desired don't match
Tested Vacuum at turbo actuator 0.6 inHg. Im use to these being around 15 inHg at idle. Vacuum to solenoid good and no leaks on pipes.
Replaced Turbo actuator solenoid with a known good. Same fault. Tried his solenoid on a donor vehicle. Works perfectly.
Duty is at 96% If I ground out the solenoid manually I get vacuum to actuator.
I have ran a new wire from the ecu that sits on top of the engine to the solenoid. No change.
Power to solenoid is good. All power & Grounds are good to ecu.
So my thinking is that the ecu is duff.
Two questions. Is there anything testing wise I could've missed. Does anybody know if the ecu requires programming to the vehicle as I can get hold of a used on from local scrappy.
I checked a combo quite a while ago, but cannot remember the engine type. More vacuum to turbo actuator caused the boost to decrease instead of the usual increase.
If the vacuum pipe had no supply it would overboost.
