I agree that this is dangerous. I have another approach that only bypasses
the fuel pump when the engine is running, as seen by the alternator before
the diodes. If anyone's interested, I send them details.
What I'm hoping is that someone will develop an adjustable overboost
protection approach that still provides protection, but at a hgher level.
It would be nice to do this without affecting the stock advance curve. Any
