Some new findings

Why do you need to extend the gauge to know what pressure at WOT?
The fuel pump produces 60 psi
When the vacuum drops to 0 (ie.disconnecting the vacuum port on the regulator) then the fuel pressure should be at maximum. For me it'* 56 psi.
With the car idling the vacuum should be highest and with the vacuum connected, the regulator should be throttling the pressure to its lowest setting. For me it'* 46 psi.
With my adjustable regulator I have it set 4 psi above what it was stock.

The o2 sensor that I took out of my car last fall was very melted, and the o2 I took out 3 weeks ago was melted also, but not nearly as much as the first.
Haven't had much driving since.
Definitely don't rule out the melted o2'* -I'd never experienced that before, but now having seen 2 in the past 6 months I definitely suggest you check it if there is reason to.

Just thought to mention a small side benefit to changing to aftermarket headers is the O2 sensor is relocated another foot further down the exhaust in a much cooler location. Most kits include the O2 sensor extension harness.
When these engines make big power, they make big heat. Darn combustion engines aren't very efficient. :?

The 94/95 Gen3 SC and TB together produce too much flow. And there are too many factory restrictions.
I'm beginning to think that the LIM and EM porting should be a requirement on 94/95 L67'* before a pulley.
