Yeah, Shane mentioned when I asked about the WG that whenever you go over double the spring pressure you might have problems controlling the boost. I have a seven pound spring in mine.

22 it does fine, but above that it seemed to just push the valve open on it's own. Too much pressure in the manifold. I played with the gain on the boost controller and it stopped doing that thing that sounded kind of like surge but wasn't. Again, the wastegate was popping open as boost was climbing and making boost come on late. Now it's like lighting off a JATO rocket.
