Angry still boost problem

hi there peeps still got trouble with my 93 wrx boosting,done a code check and was map sensor which i then replaced then did a ecu reset.
car still the same so over the last couple of days ive renewed plugs and fuel filter,removed intercooler and checked boost pipes(no prblems) checked waste gate actuator which is working fine, replced o rings in d/v and seems fine.
just dont know wot next!? code check coming bk ok. sometimes boosts to 5 psi and holds there then the next time will boost to 10/11 psi and stutters up to 15 psi not that this is the case all the time sometimes it just stutters at 10/11, any one else with any thoughts thanks. I AM TOTALLY LOST
