Drivability and fuel economy will increase and everything else will be the same, so yes it will make the same exact power and it will still fuel cut in the same exact spot, depending upon how much fuel was added with SAFC it may not fuel cut as early but instead will run leaner. Which is why you need to reduce the boost pressure.
To help you understand here is an example:
At 13psi of boost the maf may reach 4.4volts
At 15psi of boost the maf may reach 4.9volts
At 17psi of boost the maf may reach 5.1volts and FUEL CUT.
If you now install a SAFC and increase the "fuel" adjustment for 15psi, you will trick the ECU into thinking that there is actually 17psi of boost instead, and it will FUEL cut sooner because maf VOLTAGE input to the ECU is now higher.
A more appropriate way to eliminate any 12.2:1 or 12.8:1 air fuel ratios during 15psi of boost (possibly unsafe for an S15 turbo on the bleeding edge) is to bump the fuel pressure 5-8psi.
IMO that turbocharger will not last long at 15psi of boost.
