STL is right, some euro cars (Germany and GB) have the SAI system just like ours. There are several different versions of emissions tunes for Europe. Only true ROW cars (sold in middle east for example) did not have the SAI system.
ColaCharlie - do yourself a favor here. There is a diagram of your vac system in the trunk. The line that comes off of one of the bank 1 (passenger side) boots either on the plenum or resonance tube, has become dislodged. As I said earlier, it is the tubing that goes to the SAI and resonance flapper actuator, along with the vac reservoir. Study the diagram, find pics of how everything should be connected (Stl has a nice pic on the post he suggested you read) and hook your stuff up properly. Then see what happens.
This isn't rocket science. You have a vac leak on bank 1. You are leaning out and detonating (not misfiring, big difference) on bank 1. It is happening at WOT because your fuel trims can adjust for the leak while under closed loop operations. When it goes open loop (i.e. WOT) you lean out and throw the code. If you don't believe me, buy a $15 elm327 tester and download your long term fuel trim data. $5 says that your bank 1 is going to be positive and much higher than bank 2 which should be close to zero or at least very low positive single digits.

I keep looking at the picture in "Car dies" thread that your referring to and also Colacharlies picture.
In both pictures the white end of the check valve is plugged into a three way connector.
In the picture in "Car dies" thread one of the other two legs of the connector , connect to a four way connector. The vacuum canister is just to the right.
The third leg is connected to the electric /over vacuum switch that lets the resonance flapper move.
So if I understand you correctly your saying either the resonance flapper leg is disconnected or the vacuum canister leg is disconnected???
Or am I misunderstanding??
Thanks for the clarification on where the EVAP hooks in. I will check it out on my Boxster tomorrow so I have a visual.
