Default loss of boost

over the last week or so my 93 wrx has started losing boost.
its running about 0.6 at the moment but should be running 0.8-0.9 as running z4 ecu.
car has decat system,walbro pump and induction.have checked all pipes for leaks and nothing wrong.was looking at fitting a boost controller to up boost to 1 bar (and get afr checked on rollers ) as fuel cut at 1.08 bar.any ideas guys???

I just had same sort of problem with boost after fitting decat... Turned out to be my actuator sticking & boost solonoid was broken bud....

Agreed, I'd check the boost solenoid out first.
