You're gonna have to fill me in on this fuel cut at 4 psi business. I didn't realize that the 4age used any engine load sensor apart from the afm. How does the computer know about the boost?
I'm also not following what you are saying about econo fuel switches and the ECU defaulting to prem curves.

yes afm is what i mean by flap
with the motor where its at its hard to hear detonation and if you dont cach it in time you'll have a really big paper weight(aka blown 4ag)
fuel cut :the afm has a little (flap) in it in a na car the motor will only make vac to open it only so far. well with the turbo sucking in air it causes the flap (afm) to open to far this makes the ecu think there is a problem and it cuts fuel to save the motor you could try to use a voltage clamp to over come this but i think it will screw up the fuel maps any causing a new problem
the sc cars had a fuel selection switch high octane or to run low octane it changed the timing cerve for high octane had a more aggressive timing cerve for more hp because the high octane covers up the detonation
this is why i sed you can save a lot of aggravation by using the sc electronics
