Boost issue

Hi guys,
have a technical issue here and I'm sure it's down to me,
when I bought the car the boost controller played up so thought il do the old plum it in threw standard soilinoid and use a 1.2mm restrictor this worked ok to reach .9bar and like the fact still controlled by the ecu,
latley it's started dicking around only reaching .5/6bar, so cleaned the solioned out and now the car is over boosting to 1.3/4bar I was like eek!
grabbed a 3port Dawes device I had and thought right il use this and get a new avcr at some point, plumbed in the 3port. With 1.2mm restrictor , one side from plenum into bleed valve, othe to the turbo and the excess pop back into the turbo pipe, and I'm still over boosting, took restrictor out and I can't get any more than 0.6bar both stock and apexi gauge reading same, took the turbo pipe return off still exact same ,
any ideas what I've done wrong here please

Put a bigger restrictor in and run from the plenum to the wastgate actuator in one pipe.
