Including my personal logic in the last thread was a disaster, so I'll just simply ask:

1) Does anyone know if the turbo boost is controlled by the CPU in the new STi? Or is it completely mechanical?

2) Is anyone aware of companies who have already said they will build a CPU upgrade/replacement? Most of the companies that currently support the 2.0L motor are based in .jp and .au.
