Boost Problem
I've just removed a manual boost controller (dawes device) and reconnected the wastegate solenoid.
The only problem is that my car is now only generating a peak boost of 0.55 bar.
Previous to fitting the MBC is was holding a steady 0.8 bar.
Any suggestions?

Could be one of several reasons...
1. ECU has detected a problem, and now you've given it boost control again, has limited the boost (AKA limp home mode).
2. The wastegate solenoid hose isn't connected properly, so the pressure on the wastegate actuator is constant, and so the wastegate is opening at it's preset pressure (~7 psi).
3. The wastegate solenoid has clogged up because of lack of use due to Dawes, and so needs cleaning.
4. The restrictor isn't in the compressor-to-actuator hose before the T-piece.
Hopefully one of those will sort your problem!

Just had this checked by a subaru garage as the CEL won't stop flahing after an ECU reset. They can find any errors.

What does the restrictor look like?

Genius - Thanks. When I fitted the MBC is replaced some of the old hosing and didn't put the resitrictor in the new stuff.
Back to 0.8 bar now.
Just the CEL to fix!
