Only boosting 5psi

Hey so I'm having a problem i used to boost to 9psi on a 16g turbo.

So i got a short that was blowing a fuse and i found the short and replaced the fuse and got the car running. But now when i got on boost it only makes it to 5psi and wont budge.

I do have a MBC but i have not adjusted it before or after the short. I run a divorced waste gate down pipe, but it was not giving me this problem before. Any suggestions would help thanks.

I read that the VF11 wastegate pressure is 5psi and the TD05 is 9psi correct?

Yeah, the TD05H-16G has a 9psi wastegate stock. Weird. Normally I'd say that your ECU is in LIMP mode but with the 16G you should still get 9 psi. Not sure. try resetting the ECU.

Ok so i reset my easy but i still am throwing these three codes.

(24) Air control valve, (32) O2 sensor, (35) canister purge solenoid valve.

I replaced the o2 one with a used one recently and it worked for awhile but now this one has gone bad to. Also the air control valve comes and goes randomly for no reason, same with the o2. The purge solenoid valve i just tryed replacing with one from a 95 impreza motor and it still is giving me the code.

Could i possibly have the lines messed up and would that make it throw the code?

Strange.

+1 with the above you should be running more than 5psi on 16G actuator.

If you were on a Vf11 I's say it was in limp home mode....
