Mac,
I have done some research on the prodrive setup, here is a brief outline:
Port 1 ....... to turbo
Port 2 ....... to wastegate
Port 3 ....... vent to atmosphere
Please check you hose connections for me so that we are on the same page.
- When the BCS is in the un-energised state ............. boost = wastergate
- When the BCS is in the pulsing or energised state ........ boost is increased by ECU.
Here is where I got the information from:
