Trying to get my series 8 running correctly after the Apexi was stolen on Import. I have fitted a standard ECU but are having the following boost issues. These change following resetting of the ECU (battery off, battery on and idle for 10 mins)

- Boost Primary 0.5 bar / Secondary 0.5 bar
or
- Boost Primary 0.15 bar / Secondary .75 Bar

I have been over the car and have tested the black pressure box (good) and changed some lines that were getting old / brittle. I did find the check valve to the pressure box was split and have since repaired / tested this. Also cleaned all of the soldnoid plugs with contact cleaner and all of the wastegate valves etc have been checked for movement and lubed.

Am i missing anything?
