Got this pic today off the guys on turbobikes.org I had my IAP sensor plugged into one throttle body and the pulsing vacuum was making the ECU bounce around the idle map making it lean rich lean rich and so on. The IAP needs an equalised vacuum from all throttle bodies. Yet another lesson learnt for me.
If your building your own turbo kit, this will help. The x's are check valves, only vacuum to the IAP. Only boost to the FMU but it must come from the throttle body.
I was also advised to run 2 check valves on the IAP as the boost can damage the valve if you only run one.
Happy to be corrected by anyone if they see a flaw

There is no strong performance without a little fanaticism in the performer
