I think this is the key phrase here. With a small diameter pipe from the headers to the WG, this will allow overboost unless it is replaced with a larger one. I had this problem with my HFS until I did this...

Thus, the valve might open on a bench test at .7 bar bit you might get more boost in real life if you WG circuit is not ideal.
