My understanding (From Stephen) is that GHL or B&B headers flow so much better than stock headers, there's a lot more flow going to the WG. I used a .8 spring in my Tial (and GHL's) to get 1 bar.

It sounds like to me that your WG isn't functioning right. That isn't even close to your spring. You may want to look into why it isn't boosting at the spring rate. Maybe your spring is sticking? Maybe it needs to be replaced? It should be consistent with the spring. I'd be careful not to over boost. Hopefully, someone will correct me if I'm wrong.
