Get er done Chris
^ That may be true, but that's because your target boost is lower than peak boost at those RPMs. Tuners do this for one of several reasons. Now if you're running a manual boost controller (which would be a great apples to apples comparison) it will not open one bit until peak boost, that it's set to, is reached but that brings along with it the whole PTFB debate

I share a different opinion on WG size. I prefer the smallest needed for an application, which for Subarus is generally 38mm. The smaller the WG the better the fidelity, or more precise control. It's always easier to regulate a prices amount of flow/volume from a smaller valve than a bigger valve.
