John, just don't get carried away.
Matt, yes, it is potentially dangerous. This has been overlooked by all of us for quite some time. If the PCM can't dump boost before fuel cutoff, it COULD be nasty.
My suggestion is to put it back to stock (this is the vacuum line swap we're talking about, not the BCA 'loosen and turn'). You won't need it anyway if you Jet. The Jet pushes the fuel cutoff farther out of reach and deletes overboost protection.
