For all you guys that have done the 'boost bypass' trick:
And those that have, that are also running stock PCM'*:
What do you think will happen when the PCM reaches it'* fuel cutoff rpm, and your PCM can't dump boost?

We have a winner.
I never did it to the 93, as the Jet bumped my fuel cutoff out of range, and deleted the overboost protection code.
Don and I figured this out on the phone today. Talking about another member'* car. I won't be doing it to the 95.

Don and I were just theorizing about the other member'* car. This probably wasn't the cause of that damage. But it was discussed and discovered to be a possibility during the conversation.
The point is that my redline on the 95 is 6000 rpm'*, but I hit fuel cutoff at 5600. If the PCM can't dump boost before 5600, I stand a very good chance of grenading. It'* a good idea to make sure your BCS is in good working order. Sometimes damage is cumulative, and may not be apparent until weeks or months later.

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.
